Manchester big endian support (#1353)
* manchester
* Added manchester code and test

* manchester
* Formatting and added missing file

* manchester
* Some functions can only be constexpr since C++14

* manchester
* Manchester decode and some refactoring

* manchester
* Added some missing typenames

* manchester
* constexpr void function not allowed in C++11

* manchester
* condition on static_assert tests

* manchester
* revert CMakeLists.txt
* Using ETL_STATIC_ASSERT
* Some cleanup

* manchester
* Added static_assert message

* manchester
* Added compile time tests

* manchester
* Added invert manchester
* Some refactoring

* manchester
* Disable test for now
* Move ETL_NODISCARD before static

* manchester
* Test for valid_span

* manchester
* Remove redundant (?) storage specifiers for template specializations. Storage specifier already given in base template

* manchester
* refactoring to get rid of specialized template functions in template class

* manchester
* cleanup

* manchester
* Added documentation comments
* Some refactoring

* manchester
* introducing namespace detail_manchester

* manchester
* Some refactoring
* Update tests

* manchester
* Some refactoring
* Removed possible undefined behavior by refactoring encode_span
* constexpr version of encode_span
* Static assertion for rare case where code doesn't work because CHAR_BIT is not the same as the number of bits in uint_least8_t

* manchester
* renamed valid to is_valid

* manchester
* renamed is_valid_span to is_valid
* Using etl exceptions in ETL_ASSERT

* manchester
* Removed _fast functions
* merged encode_in_place with encode and decode_in_place with decode
* removed _span to create normal overloads of encode and decode for span
* Some renaming and minor refactoring

* manchester
* Fix build issues

* manchester
* Conditionally compile manchester_decoded

* Update test_manchester.cpp

Removed redundant semicolon

* #1258 Manchester coding
* Formatting
* consistency: hex literals with lower case 0x

* #1258 Manchester coding
* Moved copyright to top of file
* Make constexpr encode/decode span functions equal for little and big endian platforms

* #1258 Manchester coding
* Added missing include
* Added missing 8bit/64bit guards
* Fixed is_valid for big endian platforms

* #1258 Manchester coding
* private memcpy alias

* #1258 Manchester coding
* Review comments

* #1258 Manchester coding
* Cleanup
* Fix build error

* #1258 Manchester coding
* Add manchester documentation

* #1258 Manchester coding
* Preparation for GitHub pages

* #1324 Manchester documentation
* Some small fixes

* Print test names at test time (#1343)

* IGN-280 biphasic amplitude as float
* Add big-endian devcontainer

* manchester
* fixed the configuration to work with GitHub Codespaces. The changes use cross-compilation with QEMU emulation instead of trying to use a native s390x container.

* manchester
* Made manchester work for big-endian
* Some updates to the container

* Manchester big-endian support
* Cleanup

* Manchester big-endian support
* add sourcedirectory

* Enable running with ctest

* Manchester big-endian support
* Update documentation

* Manchester big-endian support
* QA

* Manchester big-endian support
* QA

* Enable testing with ctest with cross-compiler (#5)

* Enable testing with ctest and with cross-compiler
* Clean up includes in manchester.h
