[RFE] Presets Share

[seanwhe]

Hello and thanks for all the work on xmrig*

I really like the ability to create presets and would like to suggest an enhancement.

At present I can save a preset and load it via a browser.

This is very useful, but does not lend itself to automation such as automatically downloading programatically.

So I thought that perhaps if a URL could be provided that will result in the source of the config.json being returned it would be an advantage.

The config.json can be:

1. downloaded by xmrig
2. downloaded using ansible, bash, etc

I think that this enhancement would really improve adoption of the presets feature.

thoughts, ideas always welcome.
