v0.2.1 Update

[JakeWnuk]

• Added new transformation mode to create random passphrases based on input
• documentation

Description:
The passphrase module generates passphrases by combining words from a wordlist.
The -w flag can be used to specify the number of words to use in the passphrase.
The -tf flag is optional and can be used to specify a file containing separators
to use between words. The syntax is as follows:

ptt -f <input-file> -t passphrase -w <word-count> -tf <separator-file>

The passphrases are generated randomly by selecting words and separators from the input.
If no separator file is provided, no separators will be used. The default word count is 0.
The number of passphrases generated is equal to the number of lines in the input file
including duplicates. This means that the item count is also used to determine the number
of passphrases generated.
