Checks that the annotated character sequence is a valid UUID.

Validation characteristics:

Consists only of numbers, hex characters and dashes
Has exact length of 36 characters
Number of hex digits in every group (8-4-4-4-12)
Nil UUID (default: allowed)
Allowed UUID versions (default: 1 to 5)
Allowed UUID variants (default: 0 to 2)
Letter case (default: lower case)

The supported type is CharSequence. null is considered valid.
