Fix for 1405: etl::exchange doesn't work with unique_ptr (#1477)
* Separate bit order and endianness in bit_stream.h (#1495)
* Factor out ranges tests from test_algorithm.cpp to test_algorithm_ranges.cpp (#1497)
* Fix exchange to use forwarding reference (U&&) and move
- etl::exchange was using the copy constructor. Changed for etl::move.
- The assignment to the new object is now done with forward.
- Added a test with unique_ptr.

Fix etl::mem_cast cross-size copy constructor and assignment (#1488)
The templated cross-size copy constructor and assignment operator were
broken in two ways:
- They accessed other.buffer / rhs.buffer, which is private in a
different mem_cast instantiation, so the cross-size overloads failed
to compile whenever they were actually instantiated.
- They copied Size_ (the destination size) bytes from a source buffer
that is only Other_Size bytes large, reading past the end of the
source when the destination was larger.
Use the public data() accessor and copy Other_Size bytes. The existing
static_assert(Size >= Other_Size) guarantees the destination is big
enough.
Add test_mem_cast_copy_and_assign_from_smaller regression test.

Fix etl::pearson::reset() not resetting the first-byte flag (#1487)
reset() cleared the hash array but left the `first` flag false, so a
calculator reused after reset() took the XOR update path on its next
add() instead of the initialisation path. This produced an incorrect
hash for any pearson object that was reset and reused.
Reset `first` to true in reset() so a reset calculator behaves like a
freshly constructed one.
Add test_pearson_reset regression test.

Fix etl::bitset single-element from_string shift on empty string (#1486)
The single-element from_string overloads (char, wchar_t, char16_t,
char32_t) computed element_type(1) << (string_length - 1U) before the
copy loop. For an empty string, or when active_bits is 0, string_length
is 0, so the shift count underflows to SIZE_MAX. Shifting by more than
the element width is undefined behaviour, which also breaks constexpr
evaluation.
Guard the mask with a zero-length check so the shift is only performed
when string_length > 0. The multi-element from_string overloads were
already safe.
Add test_construct_from_empty_string regression test.

Fix etl::histogram copy/move not preserving start_index (#1485)
The run-time-offset specialization of etl::histogram stores a start_index
member used to map keys to bins (accumulator[key - start_index]). Its copy
constructor, move constructor, copy assignment, and move assignment copied
only the accumulator and left start_index uninitialized, so a copied or
moved histogram indexed the wrong bin in operator[]/add(), causing
out-of-bounds access (undefined behavior).
All four special member functions now also copy start_index. The
compile-time-offset specialization is unaffected, as its start index is a
template constant rather than a data member.
Add regression tests covering copy/move construction and assignment.

Fix etl::message_timer firing following timers early on unregister (#1484)
active_list.remove(id, has_expired) adjusts the next timer's delta only
when has_expired is false. When unregistering an active, non-expired timer,
unregister_timer() incorrectly passed true, skipping that adjustment, so
every timer after the removed one in the active list fired early by the
removed timer's delta.
Pass false instead, matching the etl::callback_timer family. tick() still
passes true, since the timer has genuinely expired there. The bug affected
all four variants: message_timer, message_timer_interrupt,
message_timer_atomic and message_timer_locked. Existing tests missed it
because they only ever unregistered the tail timer, where the delta
adjustment is a no-op.
Add a regression test that unregisters a non-tail active timer and checks
the following timer still fires at its original absolute time.
* Only enable the assign and insert member functions for class ivector<T*> & class ivector<const T*> when the value_type the iterator references is a pointer to T.
* Imporoved enable_if for assign and insert.
* clang-format
* std::void_t -> etl::void_t
* Made enable_if condition into a common class struct
