README shows different results from actual

[ggriffin]

Should I expect to get the same encrypted result as what is shown in the README?
I get 5011 instead of 4984:

$ node
Welcome to Node.js v12.14.1.
> const fe1 = require('node-fe1-fpe');
> const v = fe1.encrypt(10001, 1, 'my-secret-key', 'my-non-secret-tweak');
> console.log(v)
5011
> const d = fe1.decrypt(10001, v, 'my-secret-key', 'my-non-secret-tweak');
> console.log(d);
1

// curious what 4984 decrypts to:
> const d2 = fe1.decrypt(10001, 4984, 'my-secret-key', 'my-non-secret-tweak');
> console.log(d2);
6786

Interesting, may be a mistake, anyways it seems to encrypt and decrypt as expected.
Could you test it with buffer exactly as in the readme and if the case is still so readme will be updated.
