If `no_separators` is true, the validator will allow MAC addresses without separators. Also, it allows the use of hyphens, spaces or dots e.g. '01 02 03 04 05 ab', '01-02-03-04-05-ab' or '0102.0304.05ab'. The options also allow a `eui` property to specify if it needs to be validated against EUI-48 or EUI-64. The accepted values of `eui` are: 48, 64.

 **isMD5(str)**                          | check if the string is a MD5 hash.<br/><br/>Please note that you can also use the `isHash(str, 'md5')` function. Keep in mind that MD5 has some collision weaknesses compared to other algorithms (e.g., SHA).
