Aggregation and Sending

• aggregation – count grouped by a column, sum, etc
• sending interface redesigned – dynamic templates, step by step sending, generate e-mail preview
• daemon – since it takes around 0.75 s to start the program, notably because of the external libraries (pint, bs4, requests), when doing a single query or a headless processing (no menu involved) we may reduce this time at least ten times with a daemon that is automatically started with the first launch
• --output left BLANK causes output be piped to STDOUT instead of to a file.
• --delimiter-output, --quote-char-output, --header-output (may be set to false) to change output file syntax
• bash completion
• filter menu – now includes both exclude and include filter and unique filter
• reset menu – possibility to discard just a subset of processing settings
• tests
