Use external scanner for number literals #49

Closed stadelmanma closed 3 years ago

stadelmanma commented 3 years ago

Fixes #42 by moving number literal parsing into an external scanner. The Regexp needed to support this without an external scanner requires a look-ahead group which tree-sitter does not support.
