Integrating with other QuakeML feeds

[FoxxMD]

Other country/govs, such as the USGS in the US, provide QuakeML feeds for their regions. Would it be possible to substitute our own feed during the config process, rather than using INGV's? (This is a feature request).

If it seems like too much work I am happy to look into implementing myself and submitting a PR as I've been interested in HACS development for awhile but haven't had a chance to work on anything.

In short. I'm not a programmer, I don't have much free time anymore. Feel free to try. I would be happy if someone could make an official component, so as to replace the custom component.:sunglasses::+1:
