Minor issue with `kostkaGelfandTsetlinPatterns'`

Hello,

First, thank you for this excellent package.

I've found a minor issue in the function kostkaGelfandTsetlinPatterns' (and consequently kostkaGelfandTsetlinPatterns). The problem is that you use the minimum function:

kostkaGelfandTsetlinPatterns' :: Partition -> [Int] -> [GT]
kostkaGelfandTsetlinPatterns' plam@(Partition lambda0) mu0
  | minimum mu0 < 0                       = []

and then an error is thrown when mu0 = [].

A possible fix is to use any (< 0) mu0 instead of minimum mu0 < 0.
