Transversal overloads of builtin quantum operations

[mark-koch]

Overload single qubit operations in guppylang.std.quantum to accept arrays of qubit. Same for measurment and discarding

Before:

for i in range(n):
    h(qs[i])
for q in qs:
    discard(q)

After:

h(qs)
discard(qs)

More radical proposal: Every single argument function should automatically map over arrays?
