27f38770d4 Parentheses in macro args prevent commas from starting new arguments 
This is similar to C's behavior, and convenient for passing
function calls as single values, like `MUL(3.0, 4.0)` or
`STRSUB("str", 2, 1)`.

Fixes #704

e596dbfc80 Make failed macro arg expansions non-fatal 
Expanding empty strings is valid but pointless;
macro args already skipped doing so, now other
`beginExpansion` calls do too.

This also fixes failed interpolations (which were
already non-fatal) to continue reading characters,
not evaluate to their initial '{' character.

This combines 0.5.0 and post-0.5.0 features:
print and println, strfmt, for loops,

new macro syntax, and \<bracketed macro args>

9923fa3eee Fix expansions that start from the end of another expansion (#839) 
Do not free an expansion until its offset is *past* its size.
This means potentially freeing a nested stack of expansions

ee5da4468d Fix interpolation/STRFMT overflow issues (#838) 
Widths and fractional widths greater than 255 would overflow a
uint8_t and wrap around to smaller values.

Total formatted lengths greater than the avilable buffer size
would overflow it and potentially corrupt memory.

850c78aaf4 Report garbage chars as their bytes; don't try decoding them as UTF-8 
This decoding required high lookahead, and was not even
consistently useful (the `garbage_char` test case was not
valid UTF-8 and so did not benefit from `reportGarbageChar`).

This limits UTF-8 handling to the `STRLEN` and `STRSUB`
built-in functions, and to charmap conversion.

7e7f92f18c Assign section locations to all UNIONs/FRAGMENTs 
Fixes the test case from #800

The `out.gb` output was corrected, since the two "test"
fragments have a different order in ROM than in SRAM.
It is effectively:

; ROM0[$0000], fragments ordered by size
    jr Label
    dw Label
    db 0

; SRAM[$a000], fragments ordered by .o order
    ds 1  ; db 0
    ds 2  ; jr Label
Label:    ; $a003
    ds 2  ; dw Label
