Feature or enhancement

Proposal:

In my tests, using bytes.hex() speeds up calling the UUID.hex property.

Additionally, using the hex property and f-strings also provides some speedup in calling uuid.UUID.str.

import uuid
uuids = [uuid.uuid4() for _ in range(100000)]
t1 = time.monotonic()
for u in uuids:
    u.hex
    # str(u)
t2 = time.monotonic()
print(t2 - t1)

Results before and after the fix:

hex
before: 0.021755493999989994
after:  0.01465080400066654
str
before: 0.06381790500017814
after:  0.05134949700004654
