How it will work:

1. Installation via bot.api.config.use(filesCache())
2. Stores a number of InputFile instances based on the data they contain, ideally with constant-time lookup
3. Registers a transformer function that adds instances to the cache, and stores the resulting file identifier(s) once the upload has completed
4. Upon cache hit, the InputFile instance in the payload is replaced by the file identifier received previously if and only if the respective API method permits this according to the specs
