The tests were already made timezone-independent, but in a way that assumed
the day would still be the same and only the time would be different.
Now that assumption is removed as well.
Change the package base name of the Go code, from
`git.blender.org/flamenco` to `projects.blender.org/studio/flamenco`.
The old location, `git.blender.org`, has no longer been use since the
[migration to Gitea][1]. The new package names now reflect the actual
location where Flamenco is hosted.

Initial implementation with some basic tests.
The API command only accept one source and destination path, which must
be absolute. If the destination already exists, it will not be
ovewritten, and an error is generated.
JS job definition code using this new command can easily handle list of
paths and/or relative paths if needed.

Introduce `ParameterMissingError` and `ParameterInvalidError` structs, to
be returned from command executors. These replace free-form `fmt.Errorf()`
style errors.
