Adds query to transaction and refactor transaction to reuse the get etc functions

[ftzi]

Queries can be used in transactions if running on server, as I read and tried (haven't tried on client yet but working on server). #6 #95

Also, as you mentioned in the code, you rewrote the get etc functions inside the transaction.

typesaurus/src/transaction/index.ts

Lines 308 to 311 in e4c2fa3

	// ^ above
	// TODO: Refactor code above and below because is all the same as in the regular get function
	const firestoreSnap = await t.get(firestoreDoc)
	// v below

I have made a quick workaround so both get() and transaction's get() uses the same common function. Done the same for query(). It can also be done for the other transaction functions but won't do it until you think it's a good idea.

This branch is working but leaving as a Draft until further discussion and maybe improvements.

I had to as any because all those generics and overloads of get weren't matching, but it's the same params order. Tried to get it working without the type cast but hadn't success.

Also, I props[0], props[1], props[2] instead of ...props because some of them are optional and would make {a, t} be in the wrong param instead of the forth one.
