"from_lark()" could generate strings which the grammar's lexer
tokenizes differently than the terminal they were generated for, and
which therefore fail to parse - for example "'"""'" for Lark's built-
in "ESCAPED_STRING" terminal (issue #4325). Terminal strategies now
only generate strings which the lexer would match in their entirety.
