This adds support for a dedicated ignore file by the name of `.ignore` a
la `fd`, `ripgrep`, et. al.
This purely just mimics what `Gitignore` is doing except it doesn't
ignore `.git` directories. There might be more I need to tweak and the
interface might be too obtuse, but this is a first pass.
I've also added a `--no-ignore` flag which ignores both `.gitignore` and
the dedicated `.ignore`. It might make sense to add a specific flag that
ignores `.ignore` but respects `.gitignore` to support the old
behaviour, but I wasn't sure what to name it.
Instead of special-casing the callback, which is the path least-taken,
switch the internals to a Handler model, where the default behaviour is
an implementation of a Handler, and external callers can implement their
own Handlers and pass them in.
While doing so, change all unwraps in run::run to returning Errs, and
expand the watchexec Error enum to accommodate. That should make it
easier to use as a library.
Also, differentiate between "manual" and "on update" runs. For now the
only manual run is the initial run, but this paves the way for e.g.
keyboard- or signal- triggered runs.
