Add mappings for reset branch and cherry-pick

[AlterDepp]

Add three new mappings:

• rb: Git reset %h
• rbh: Git reset --hard %h
• cp: Git cherry-pick %h

Thank you for your contribution.

However, I'm sorry, I usually avoid adding new bindings to Flog to avoid any potential conflicts with future Fugitive bindings. I try to keep bindings as close to Fugitive as possible - the pro is that it's familiar to new users coming from Fugitive, the con is that we have to be very selective or risk confusing users in the future.

To add new bindings, I would need either:

• A reason that the binding is not likely to conflict with Fugitive, such as if an equivalent binding is already in Fugitive, or if Fugitive uses the binding for something else which Flog can't add an equivalent for.
• An extremely compelling reason why the binding is needed for basic functionality.

You might be able to get git reset bindings added to Fugitive first, in which case I would add them here.

Cherry-pick on the other hand has no reason to exist in Fugitive because it can't view other branches in its status window. I would love to find a safe binding to add it to Flog under, but I haven't found anything yet. Maybe it's time for me to create a secondary plugin with more (unsafe) bindings, but there's really only a couple that would be useful that I can think of right now.

The alternative is to add these bindings to the Custom Commands wiki article and keep them in your vimrc. The wiki is publicly editable.

Aren’t the bindings local to the flog buffer? So they should not conflict to other bindings.

It's not about conflicts, it's about familiarity and parity with the parent plugin of this plugin.
