Create encrypt-data-using-rc4-via-systemfunction033.yml

[dstepanic]

Hi,

This rule is pretty much a duplicate of the existing rule (SystemFunction032), it's paired with another undocumented API (SystemFunction033) that implements encryption/decryption using RC4 algorithm. Thanks!

please rename per the lint info:

• FAIL: filename doesn't match the rule name: Rename rule file to match the rule name, expected: "encryptdecrypt-data-using-rc4-via-systemfunction033.yml", found: "encrypt-data-using-rc4-via-systemfunction033.yml"

I've added the testfile to capa-testfiles.
