* generalizes and extracts CacheDb accessors from Make

This is so they can be used from within the IDE as well, which doesn't
run in Make

* overwrites ContentHashes and Timestamps for rebuilt modules

* removes a whole lot of "Christoph didn't know what he was doing"

* reorganizes the cache info building

* normalises filepaths before inserting them into the Cache

* normalise file paths when rebuilding from the IDE

* extracts the logic that updates the Cache

* inlines function that I didn't up using in the IDE code

* cleaner diff

* more simplifications

* Update src/Language/PureScript/Make/Cache.hs

* [purs ide] Tracks the cache-db.json timestamp

This allows us to trigger a full reload when someone other than the
IDE invoked the compiler

* fixes tests

* [purs ide] removes editor mode flag and the file watcher

The editor mode functionality is the default now, and we're checking
the cache-db.json timestamp to invalidate our externs store instead.
This means we can get rid of the flaky file watcher

* Formats the Ide.Types module into how I'd write Haskell today

makes the formatting consistent within this file at least

This commit changes the encoding for externs from JSON to CBOR. We're using the serialise library to derive instances for all the relevant data types.

By doing this we're getting significant speedups in IDE startup time, but also in the normal compiler pipeline.
The performance measurements in this PR measure how long it takes to load the fully built pscid project and populate the IDE caches. It's dominated by the time it takes to deserialise the externs files, and drops from 3.5s to 0.55s. Memory allocations drop from 8,460,187,856 bytes to 1,649,605,704 bytes.

* Represents ModuleNames as a single Text

The hierarchy `[ProperName]` suggests doesn't actually exist except
for the `Prim.` namespace. The compiler compares module names for
equality and ordering all over the place though, so we should pick a
representation suitable for that.

* preserve CoreFn encoding

* [purs ide] Extracts documentation comments for type classes

I had assumed we were already doing this? Maybe something about the
Name structure changed.

* [purs ide] Extracts documentation comments for type class members

* Fix CoreFn version parsing and add test

* Move parseVersion' to CoreFn.FromJSON module

This commit adds support for optimizing functions that contain local
functions which call the outer function in tail position, as long as
those functions themselves are only called from tail position, either in
the outer function or in other such local functions.

This enables hand-written mutually-tail-recursive function groups to be
optimized, but more critically, it also means that case guards which
desugar to use local functions don't break TCO.
