fluent4rs 2.3.1

Parser / codec for [Fluent FTL files](https://github.com/projectfluent/fluent/blob/master/spec/fluent.ebnf), written for [lingora](https://github.com/nigeleke/lingora) (a localization management program), and may be found to be useful outside of that context. It is not intended to replace any aspects of the [fluent-rs](https://github.com/projectfluent/fluent-rs) crate implemented by [Project Fluent](https://projectfluent.org/), and, for the majority of language translation needs, the reader is referred back to that crate.
