Parse cards out of deck descriptions.

Now that the secret lair drops are uploaded, many of them reference bonus cards in the DISPLAY field. All such cards take one of two forms:

• [SLD:123] for a specific card
• [SLD:123-145] for a range of possible cards

Turning these into functional links would be a useful tool. Also useful would be something like [MOM:id=u r>=r] to search for the blue jumpstart random rares.

So there are two ways:

• either some syntax that works both ways like [SLD:123] Island - this is a bit awkward, as we can't make "Island" into a link as we don't know where it ends
• or something like markdown link syntax [e:SLD number:123-145](My Little Pony basic lands), which would need additional markdown parser step. Or [https://mtg.wtf/card?q=e%3ASLD+number%3A123-145](My Little Pony basic lands)

If it's mostly single cards, we can have special syntax, but if we get to [MOM:id=u r>=r], might just as well make it a link.

Then again, embedded links wouldn't work great if we wanted to export this data somehow.

I figured it would just leave the [SLD:123] in place as the link, and the text around it could be whatever.

Seems to be working on all the secret lairs I checked. I'm closing this as complete.
