Close #1205

TODO:

  • Frontend implementation
  • Backend implementation
  • Ensure that ideally the filename on disk is the same as specified by the user in most cases
  • Testing
  • Merge Clearly fail when users select a wrong backend #1214 first (they would conflict else)
  • What to do for Series("asdf.bp5", Access::CREATE, "adios2.engine.type = \"file\"")?
    Current implementation: Accept this in the backend, but warn the user that the file engine will decide the BP version independent of the extension: [ADIOS2] Specified explicit ending '.bp5' in combination with generic file engine 'file'. ADIOS2 will pick a default file ending independent of specified suffix. (E.g. 'simData.bp5' might actually be written as a BP4 dataset.)
  • Test that Series("asdf.bp5", Access::CREATE, "backend = \"adios2\"") is handled correctly
  • Merge Fixes for BP5 engine #1215 first and delete those commits from this branch
  • Documentation
  • Merge BP5 tests: Only run them if ADIOS2 has BP5 #1262 first
  • extend openPMD::getFileExtensions()
  • Merge Distinguish all char types in ADIOS2 backend  #1275 first

Current approach: Each ADIOS2 engine has a set of accepted file endings and a default file ending. If the user specifies any of the accepted endings, it will be used. If no ending is specified or any other ending is specified, the default ending will be used.
E.g.: Engine "file": default ending "bp", accepted endings "bp", "bp3", "bp4", "bp5"
Engine "bp4": default ending "bp4", accepted endings "bp", "bp3", "bp4", "bp5"

This PR now has some BP5 fixes that I'll need to factor out.

CI looks good, but I'll run it again to make sure it's up-to-date.
