[PATCH] New customization: `piem-default-branch-prefix'

Hi,

Upon using piem for some time, I am getting hundreds of generated
branches in my repos. It gets inconvenient after some time, especially
because the branches are not always clearly distinguishable.

I'd like to add a new customization that adds a custom prefix string to
the generated branch names. That way, I can easily see the branches
generated by piem in the list of branches, nicely grouped when sorting
alphabetically.

The patch is attached.

Subject: [PATCH] New customization: `piem-default-branch-prefix'

* piem.el (piem-default-branch-prefix): New custom option adding extra
prefix to the generated default branch name.  Only takes effect when
the default `piem-name-branch-who-what-v' is used as
`piem-default-branch-function'.
(piem-name-branch-who-what-v): Use the new customization.
