Records and silenced echoes

New features:

• reading of records (non-interactive mode) from stdin, line by line, e.g. like comma separated values (CSV-file)
  • whereas parameters (switch -r) determine with which character sequences the values are a separated
  • whereas parameters (switch -p) can select which columns of the records are taken for references and which are taken as passwords
  • whereas switch -l causes to display only passwords that are found in the datasets of leaked passwords
• interactive mode comes in two versions without echo (switch -i) of the password or with echo (switch -ie)

Known design weakness:

• usage of System.IO.Unsafe.unsafeInterleaveIO in file PwnedKCore.hs

Test coverage:

• some manual tests, without protocol
• usage of KeePass (https://keepass.info/) exports and examples as documented in README.md
