will do that, making the life of lib/expr easier.

lib/parse: make parseLiteral a little tighter
...
Sub-parsers are seldom used by themselves, except for parseDecimal.
I'm tightening the code of this unit for two reasons:
1. Optimization
2. Upcoming API change where HL won't be preserved anymore, but will
point to char following the last parse char. This will allow us
to simplify lib/expr.

lib/expr: make recursion process a bit more orderly
...
Instead of going left and right, finding operators chars and replacing them
with nulls, we parse expressions in a more orderly manner, one chunk at a
time. I think it qualifies as "recursive descent", but I'm not sure.
This allows us to preserve the string we parse and should also make the
implementation of parens much easier.

test: begin adding common test harnessing code
...
This should make tests a bit more convenient to write and debug.
Moreover, begin de de-IX-ization of parseExpr. I have, in a local WIP, a
parseExpr implemented using a recursive descent algo, it passes all tests, but
it unfortunately assembles a faulty zasm. I have to find the expressions that
it doesn't parse properly.
But before I do that, I prefer to commit these significant improvements I've
been making to tests harness in parallel of this development.
