FilterPayloads

The payload each built-in filter takes, used to type `FilterManager.set` and `FilterManager.get`. Keep an entry per {@link FilterType} member. A name missing from here (and from `CustomizableFilters`) resolves to `unknown`, which is what lets unregistered filters be set with any payload. Note `Echo` and `DSPXEcho` differ: both are written to the wire as `echo`, but the `lavalink-filter-plugin` one takes `{delay, decay }` and the `lavadspx-plugin` one `{echoLength, decay }`.
