Update lexer_state to lexer_thread to avoid deprecation warnings

[geographika]

When running pytest on modules that depend on Lark I'm getting 100s of deprecation warnings:

lib\site-packages\lark\parsers\lalr_interactive_parser.py:27: DeprecationWarning: lexer_state will be removed in subsequent releases. Use lexer_thread instead.
    warnings.warn("lexer_state will be removed in subsequent releases. Use lexer_thread instead.", DeprecationWarning)

Raised at:

lark/lark/parsers/lalr_interactive_parser.py

Line 24 in 7043c3e

warnings.warn("lexer_state will be removed in subsequent releases. Use lexer_thread instead.", DeprecationWarning)

These appear to come from the use of lexer_state within Lark. Updating to lexer_thread in resume_parse removes these errors.

Great, thanks!
