Normalizer fails to parse qualified identifiers with mixed quotes (e.g., example_schema."some-table") #117

The sqllexer normalizer incorrectly rejects identifiers that combine an unquoted schema/table name with a quoted table
name, such as: example_schema."some-table"

During tokenization, after encountering the . the normalizer treats the following " as the start of a quoted identifier, but the hyphen - is being interpreted as the end of the quoted identifier, which is incorrect. The lexer should continue until it finds the matching closing ", regardless of the characters inside.

Reproduction steps:

• Try to lex example_schema."some-table";. (see tests in Fix: Handle mixed quote qualified identifiers #116)
  The resulting token is incorrectly example_schema."orders.

• Try to lex "example_schema".orders_underscore (see tests in Fix: Handle mixed quote qualified identifiers #116)
  The resulting token is incorrectly example_schema.
