feat: lxfml splitting for bbb (#1877)

Browse Source 
* LXFML SPLITTING
Included test file

* move base to global namespace

* wip need to test

* update last fixes

* update world sending bbb to be more efficient

* Address feedback form Emo in doscord

* Make LXFML class for robust and add more tests to edge cases and malformed data

* get rid of the string copy and make the deep clone have a recursive limit

* cleanup tests

* fix test file locations

* fix file path

* KISS

* add cmakelists

* fix typos

* NL @ EOF

* tabs and split out to func

* naming standard
