Add Uri with support for regexUri and globUri

Add support for regex uri and glob uri.
This pull request is a combination of:
#5214
#5467

There is an issue when importing <regex>

[Bmooij]

BTW it is not tested on a real device, because I don't own an esp8266

@Bmooij How did you test it if not on real esp8266 ?
Do you know you can test that kind of code on your dev computer using emulation on host (cd tests/host/; make) ?

[Bmooij]

I tested a similar implement on my esp32

But emulating sounds interesting. I will look into that later.

@Bmooij there seem to be some warnings (unused params)

Fixes #2019

There is an issue when using the regex lib for esp8266
See: #6952

[Bmooij]

I replaced the <regex> lib, with <regex.h> because it crashes and it has limitations. See #6198 (comment)

I tested it with an esp8266.
Everything works as expected now!

Very cool, works well. I did a couple trivial tweaks to the example to match the others instead of bothering you for them, but it all looks good.

Only thing missing is some documentation, but the example does show what I think would be a couple common use cases, so approving. We may want to open up a new bug to update the docs with these new calls, but that shouldn't impede this one.
