Add component support

[poVoq]

Seems like there was a really old PR that partially implemented this already: #75

Initially we thought about moving to Mellium for Matterbridge because component support would be quite useful, but with that above partial implementation existing it might not be so hard to get working in this library?

I don't think I will find the time to work on this in the near future. Do you plan to work on this?

Me personally no (very limited Golang knowledge), but we have some people contributing to the new Matterbridge fork that might look into it.
