Invalid `tsquery` output

[apoorv-mishra]

Invalid tsquery output given for the following case,

const tsquery = require('pg-tsquery');
console.log(tsquery()("env\\: *")) // env\ – note that `:` and `*` are missing

Unfortunately I don't have enough time to work on this, the regexes config https://github.com/caub/pg-tsquery/blob/master/index.js#L56-L64 can probably be adjusted to handle such case

I think adding the backslash \\ in word regex should do it if you expect "env:" as a result, let us know how it goes please
