Integrate a copy of EmbedIO library inside BlazorMobile

Integrate a copy of EmbedIO library inside BlazorMobile.

The main purpose of this action is not to prevent any advertising of EmbedIO library in the package, as it will be mentionned on the README page, but to be able to use another version of the EmbedIO library when using BlazorMobile.

If the end-user update the EmbedIO library for its usage, BlazorMobile will surely broke as EmbedIO library tend to often have a lot of architectural change, and so, breaking changes for our plugin if it's updated.

The goal of this issue is:

• [ ] Fork EmbedIO
• [ ] Add it in the project source code
• [ ] Rename namespaces
• [ ] Add the modified version of EmbedIO in the package
• [ ] Remove EmbedIO reference in nuspec(s)
