The validator incorrectly accepts lowercase hash algorithm names, which is not compliant with the specification.

[railisac]

The README.rst has this example

$ validate-patterns
Enter a pattern to validate: [file-object:hashes.md5 = '79054025255fb1a26e4bc422aef54eb4']
PASS: [file-object:hashes.md5 = '79054025255fb1a26e4bc422aef54eb4']

However, according to Section 10.7 "Hashing Algorithms" of the Specification, hash names need to be uppercase, i.e., file-object:hashes.MD5. The lowercase version from the example is not valid.
