AllFilesChanges support nested packages

#9

v1.2.0

• Updated to go 1.20
• --all-files flag for checking for any changed files, not only .go

Detect changes in external modules' subpackages

Previously patrol would only catch a dependency upgrade in go.mod if a
local package was referring the top-level package in that dependency.
For example if your go.mod looked something like:

module github.com/your-org/your-module

go 1.17

require github.com/another-org/their-module v1.8.0

And you were to upgrade github.com/another-org/their-module to version
v1.8.1, only the packages in your module relying on
github.com/another-org/their-module would be marked as changed, while
packages depending on other nested package in that dependency wouldn't
(e.g. github.com/another-org/their-module/writer).

Patrol 1.0

Support references other than commit has

This enables support for flexible references, such as:
HEAD, branch, tag, heads/branch, refs/heads/branch, refs/tags/tag,
refs/remotes/origin/branch, refs/remotes/origin/HEAD, tilde and caret
(HEAD~1, master~^, tag~2, ref/heads/master~1, ...), selection by text
(HEAD^{/fix nasty bug}), hash (prefix and full).
