html-to-jsonml

A simple parse5-based library for converting HTML text to
JsonML. Developed for Webstrates, but can be
used for anything JsonML-related.

This replaces the htmlparser2-based
jsonml-parse module we previously used, because of
its issues parsing
`

Into

`json
["script","var x, y, z = x ","< y;"]
`

Whereas this library gives you

`json
["script",{},"var x, y, z = x < y;"]
`

With more complicated script code, this gets even worse with jsonml-parse, resulting in odd and
complicated objects, rather than plain text as it should be.

To be fair to jsonml-parse, this is not an issue with the module itself, but with the the
underlying htmlparser2.

Additionally, it's worth noting that html-to-jsonml (at the time of writing) takes up 459 KB: 29
KB of which is this library itself, and 430 KB on parse5. In comparison, jsonml-parse uses a
total 2.6 MB.

Very brief and initial testing shows that jsonmlParse appears to be slightly faster than
html-to-jsonml`, though.
