[deps] Switch to lark

[marius-alex-tache]

Hi,

Is there a chance to switch to https://pypi.org/project/lark/ instead of lark-parser? Is it doable or it's too much work? We have commentjson as a dependency in one of our Python tools, but the lark-parser dep conflicts with lark dep used in another project. Please let me know.

Best regards, Marius
