[FEATURE] Use configuration from query file header

[JCZuurmond]

A user can define configuration parameters in the query header. The configuration is stated in the commented lines in the header.

@nfx : Have you settled on a preferred format for the configuration? I am leaning towards argparse:

-- --width 10 --height 3

*/
--width 10 --height 3
/*  

IMO json is to verbose and yaml covers too many lines. Also, I prefer argparse over custom parsing like the one in ucx

[nfx]

@JCZuurmond let's go with argparse, it's good enough for what we need. /* --width 10 --height 3 */
