Lookbehind in number regexp crashes Safari

[tmadeira]

Describe the bug
The regular expression at https://github.com/scriptcoded/sql-highlight/blob/master/lib/index.js#L42 uses lookbehind, which is currently not supported by latest Safari (https://caniuse.com/js-regexp-lookbehind) and some other browsers; caniuse says that its global support is 76.9%. Safari considers that the code has a syntax error, crashing the page.

To Reproduce

1. Import sql-highlight getSegments in your browser bundle.
2. Load your page on Safari.
3. Page crashes with "syntax error: invalid regular expression: invalid group specifier name".

(Or just type /((?<![a-zA-z])\d+(?:\.\d+)?)/g on Safari console.)

Expected behavior
Code should compile.
