Allow generation of changelog for specific components

[OddBloke]

I have a workspace that contains a library and a binary (distro-info and ubuntu-distro-info respectively in the examples below). These are released as separate crates, so I would like to maintain their changelogs separately, to make it easier for users of each separate component to understand what it is that changed. I'd like to be able to invoke clog-cli something like this:

clog -r https;//github.com/OddBloke/distro-info-rs --component distro-info
(cd ubuntu-distro-info;
 clog -r https;//github.com/OddBloke/distro-info-rs --component ubuntu-distro-info)

For changes which affect everything, I would like to be able to use an "all" component, so being able to specify more than one component would be ideal:

clog -r https;//github.com/OddBloke/distro-info-rs --component distro-info --component all

(Potentially there could be a way of including/excluding the empty component, which could allow it to serve as the "all" component.)

+1 for this, I'd really like to see a feature like this for releasing tokio-console (which consists of multiple crates). I'd be happy to work on implementing a feature like this.

PRs welcome :D

Great --- I might have some questions :)

Cool! I'd be happy to help. I mean, I haven't worked on this for many years but I'd be honored to be of service for tokio :)
