ez: add b4 -F to allow (re-)creating branches from threads

It is now possible to create a b4-tracked branch from an arbitrary
thread (or from a previously sent b4-tracked series):

    b4 prep -F [msgid-of-the-series]

Example:

    $ b4 prep -F 20220901194310.115427-1-tony.luck@intel.com
    Grabbing thread from lore.kernel.org/all/20220901194310.115427-1-tony.luck%40intel.com/t.mbox.gz

    NOTE: any follow-up trailers were ignored; apply them with b4 trailers -u

This makes it easier to start tracking pre-existing series with b4 prep.
