[Feature] Support Ortho4XP provider files

[stackTom]

Motivation

Add more providers from which to obtain imagery.

Detailed design

Add support for parsing Ortho4XP .lay files

Alternatives

Less servers from which to download scenery.

More detail (optional)

Is there any interest for this? I am considering doing a pull request for this, so that we are able to use .lay Ortho4XP provider files and thus have access to a larger amount of servers to use.

I have no idea about Ortho4XP, could you give me more information about this? And yes if you can do a pull request that's very welcomed.

Ortho4XP has a .lay file format with a collection of a bunch of files describing servers from which to download satellite imagery I wrote a basic parser in C# so that FSEarthTiles supports .lay files. I imagine writing a parser for msfs2020-map-enhancement should be even easier, since the code handling this is written in python, correct? (Ortho4XP is also written in python).

Here is an example .lay file: https://github.com/stackTom/Ortho4XP_FSX_P3D/blob/master/Providers/United_States/USGS.lay

I see it is a url template to provide satellite imagery providers and the format is quite easy to parse. I'm going to have a look. Btw, I'm going to make a pro version which support new features and this file format give me some tips :)

Yes, would be great if you add it. Might need a custom solution if you plan to sell this feature. But definitely having more providers would be great.

@stackTom although it is different implementation, the custom map may help: https://github.com/derekhe/msfs2020-map-enhancement/wiki/Custom-map-editor
