Needed something like this library

[getify]

I recently needed something like this library. My use-case is converting numeric sentences from speech-recognition libraries (like PocketSphinx.js). Unfortunately, after surveying this library, I had several concerns and unaddressed wants:

• Several open/unaddressed bugs reported and not triaged for quite awhile -- is this project still maintained?
• A few known-unsupported conversions (listed in the tests)
• Supporting a few looser forms of english number sentences
• Exact outputs (via string) instead of as numbers (with floating point quirks)
• Operate in a mode that errors if contents in the string aren't recognized as valid (such as "four thousand six million")
• Ability to collect individual digits as a single number (like "one two three four" -> "1234")
• Able to specify an optional formatter option: unit-place separator (,)
• Zero-dependency lib that could run in the browser with no build-steps/etc
• Wanted to expose an AST result from parsing such that other number formatting/localization would be possible as custom serialization from the AST
• I did not need/want the fuzzy matching or the multiple numbers per string features -- wasn't clear if I could disable those?

In the end, I decided to implement a parser/compiler to suit my needs, rather than adapting this library from its current form. Just wanted to share my efforts in case they're useful to anyone (including this project):
