BREAKING: metro: rename 'unbundle' to 'ram bundle'

Summary:
@public

Let's get rid of the "unbundle" terminology and instead use "RAM bundle", short for "Random Access Bundle" format. THIS IS A BREAKING CHANGE FOR OSS, as the command becomes `ram-bundle` instead of `unbundle`. It realy shouldn't be a command to start with (only a "format" specifier for the `bundle` command), but I don't want to do that change at this point.
