- version update to 2.1.0
### Added
- Added new function `textx.scoping.is_file_included` ([#197]).
### Changed
- Allow passing kwargs (specially - file_name) argument when loading metamodel
from string (needed for `textX-LS v0.1.0`) ([#211]).
- Changed the parser rule for regex matches. Spaces are not stripped any more
from the beginning and the end of the regexp-pattern. This could be possible
**BIC** for some special cases [#208].
- Changed function name `textx.scoping.get_all_models_including_attached_models`
to `textx.scoping.get_included_models` (marked old function
as deprecated) ([#197]).
- Delete all models touched while loading a model, when an error occurs
while loading in all repositories (strong exception safety guarantee) ([#200]).
