Restructure pipeable/module implementations for all adts.

[baetheus]

Currently, the Type Class instances contain the canonical implementation of their associated functions. ie (for option.ts):

export const Functor: TC.Functor<URI> = {
    map: (fai) => (ta) => isNone(ta) ? ta : some(fai(ta.value)),
};

export const { map } = Functor;

Currently, the deno docs tool doesn't like the typing on export const constructs, let alone the destructured export consts. Thus, this issue if meant to track migrating the canonical map, ap, of, etc implementations to export functions like so:

export function map<A, I>(fai: (a: A) => I): ((ta: Option<A>) => Option<I>) {
    return ta => isLeft(ta) ? ta : some(fai(ta.value));
}

export const Functor: TC.Functor<URI> = { map };

This should allow us to pick up at least the type information in the automatic doc generation. Incidentally, this will make the types on the pipeable exports look nicer too. The downside is that the types for each function export must be declared manually for every function (as opposed to inferred from the eg TC.Functor<URI> type.)
