Convert Uncle-Clive's JSON into something suitable for Pokrovsky's Github vandalism
A very simple webservice to take the 8-unit-high output from Uncle-Clive and convert it to 7 units for use in the Pokrovsky Github vandalism service, according to the following rules:
- if a character has a blank top row, that row will be excised, else
- if a character has a blank bottom row, that row will be excised, else
- rows will be excised
Will return JSON content representing :text, rendered in the 1982 Sinclair Spectrum character set, but compressed into 7 rows, and with the 'on' pixels represented by 4s.
