fix: miscellaneous

- 'stt' should not trigger 'tt'
- use \mathbb whenever possible
- move 'inf' to no_backslash
- math_wrA: fraction should encompass backslashes (e.g. \pi -> \frac{pi}{})
- set: correctly escape backslashes

fix: greek snippets

- missing uppercase sigma
- missing pipe preveting gamma/iota from expanding
- theta/zheta should take priority overe eta
- psi prevents typing epsilon
