Add L-STR and CS-STR types to specializations

[davidhassell]

• [x] Update types in specialization files ...
• [ ] ... and provide tooling to interpret them

Both of these will map to 'str', but provide downstream tooling with flags on how to render questions.

'l-str' (long string) will imply a larger entry box and encourage up to a "long paragraph" of text - useful for overview properties.

'cs-str' (comma separated string) will imply a 0.1 or 1.1 string that should contain a CSV (e.g. "NOx, NOy"). At some stage (but not now) these may be split into proper lists, e.g. by the comparator.

• [x] The few occurences of 'str', '0.N' will be replaced with 'cs-str', '0.1'.
