feat: add tag.output to manage the tag output

[djgilcrease]

• tag.output is required for mono repo structures if I need to run

  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. So now I can do

  svu n --tag.prefix foo/v --tag.pattern 'foo/v*' --tag.output='v' --log.directory foo > foo/.version
  svu n --tag.prefix bla/v --tag.pattern 'bla/v*' --tag.output='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}

• fixes consider making config an argument #203 --config to be able to have multiple config files to make monorepo usage easier

• I made sure the log.directory config entry works as relative to the config path so you can do
  ui-service/.svu.yml ->

  always: true
  tag:
    pattern: ui-service/v*
    prefix: ui-service/v
    output: ''
  log.directory:
    - "../uilib"
    - "."

  OR
  .ui-service.svu.yml ->

  always: true
  tag:
    pattern: ui-service/v*
    prefix: ui-service/v
    output: ''
  log.directory:
    - "uilib"
    - "ui-service"

I think you can simply set tag.prefix to an empty string 🤔

[djgilcrease]

No, because the repo has 56 modules in it needing the tag prefix since they are released independently and when I tried setting the tag pattern with no tag prefix it complained about not finding any matching tags to version bump

[caarlos0]

maybe then we split --tag.prefix into --tag.prefix.input and --tag.prefix.output or something like that?

Or even make it a slice, so it could have --tag.prefix=input,output 🤔

I like this, but will do --tag.prefix && --tag.prefix.output, will rework the PR and make output default to --tag.prefix

[djgilcrease]

Updated and it ended up being --tag.output since --tag.prefix.output did not parse properly with --tag.prefix being a string and I felt --tag.prefix.input was ugly AF and would be a breaking change.

this can be removed i think
