Feature: Select supported cards based on AID

[Muzosh]

I have created this draft PR to layout very basic changes for Web-eID to be able to work with smartcards based on application AID installed on the card, not the ATR itself. Related to #38

Hi @mrts, I was wondering:

Instead of trying to list all AIDs located on the card (which I don't know if it's even possible), it might be easier to implement simple repeated SELECT + AID from hard-coded list of supported AIDs.
If the card returns SW 0x9000, the applet is located on the card and the Web-eID can claim this card to be supported.

Here's my question to your or anyone else working on the Web-eID (I do not have this knowledge or experience to know this):
Is this approach safe for the smart card integrity? Can a general smart card handle multiple repeated requests to select some applets? Is it possible, that with some huge "supported-AIDs" list defined in the Web-eID, it might somehow block the smart card by triggering some kind of brute-force protection?

Best Regards,
Petr.

STATUS UPDATE:
I'm not that experienced with modern C++ coding, but to my eye these changes seem OK. However, during simple testing, it managed to hog the memory of my mac very very fast, so there are definitely some issues in the code.

This should be reverted to the original relative path.
