[Feat]: Table Numbers as Round Identifiers

[TylerBloom]

Description:

Often, table numbers suffice as round identifiers for active rounds. This should be supported by SB (and SquireLib).

The solution you'd like:

To specify a table number, the number can be prefixed a T in order to distinguish between round numbers.

Alternatives:

Alternatively, match numbers are likely to be used less as identifiers, so we can default to table numbers and use R and/or M to specify match numbers.
