`wast2json` fails to parse `if.wast` from latest testsuite about wabt

[keithw]

Yes, here is the upstream addition to the testsuite: WebAssembly/spec#1682

Will have to take a look at the WAT parser (wasm-tools already fixed this here, which maybe we can use as inspiration: bytecodealliance/wasm-tools#1215).

Unfortunately this isn't the only change in the testsuite repo that will cause issues; the new testsuite also upgrades the exception-handling proposal to "v4" of that proposal (adding try_table, eliminating try_catch & try_delegate, and restoring exnref), which is going to require a bunch of work in the text/binary readers and writers, interpreter, and wasm2c to support

Thanks for the quick turnaround!
Do you have already a release date in mind?

[keithw]

Not really -- if this is something users are clamoring for, we could cut a release right now.

Just nice to have from my side, I'm not blocked 👍
