feat: add tag.output to manage the tag output (#228)

* feat: add tag.strip-prefix bool

* tag.strip-prefix is required for mono repo structures
	if I need to run
		```shell
		svu n --tag.prefix foo/v --tag.pattern 'foo/v*' --log.directory foo > foo/.version
		svu n --tag.prefix bla/v --tag.pattern 'bla/v*' --log.directory bla > bla/.version
		export BLA_NEXT=$(cat bla/.version)
		export FOO_NEXT=$(cat foo/.version)
		docker tag foo foo:${FOO_NEXT}
		docker tag bla bla:${BLA_NEXT}
		```
	I do not want FOO and BLA _NEXT to have the prefix

* added --config to be able to have multiple config files to make monorepo usage easier

* chore: address comments from PR

* chore: remove StripPrefix flag as it isnt needed

* chore: address lint issues
