bug(developer): compiler generates invalid javascript for unquoted numbers in `if()` statements

[mcdurdin]

Describe the bug

if(option_key_t_is_tyun = 1) U+221A + [NCAPS K_T] > set(option_key_t_is_tyun = '0') save(option_key_t_is_tyun)

This generates invalid javascript: it generates a store with a value of "\x1", which must be "\x01" to work.

The source keyboard: armenian_mnemonic from https://community.software.sil.org/t/text-suggestion-not-working-in-some-cases/6490/4 (armenian_mnemonic.zip)

Proposed mitigations:

1. always generate minimum 2 char hexadecimal sequences.
2. possibly, hint that an unquoted number might not be expected?
3. not really related, but compress the list of compared store values so we don't end up with hundreds of them in the compiled keyboard.
