Thomas Weber 3aca9363a3 Optimize jsexecute helpers (#389) 
* replace Number.isNaN -> x !== x (see https://github.com/TurboWarp/scratch-vm/pull/367 for background on this though it matters less than expected)
 * optimize listGet for numbers
 * optimize listReplace for numbers
 * optimize listDelete for first and last items
 * optimize listContains / listIndexOf by hoisting work that would previously happened inside compareEqual many times

Thomas Weber 925f113400 Don't start monitors if there are no targets 
Fixes https://github.com/TurboWarp/sb3fix/issues/125 in the safest way that
hopefully has no unforseen breakages on weird behaviors

Thomas Weber 9f2106a290 Remove variable value safe stringification 
I thought this may have been part of fixing a sb2 -> sb3 corruption issue.
But from commit log, it seems this was added to prevent extensions from making mistakes.
With the scratch-parser change, those mistakes are now considered features.
Seems safe to just do remove these checks all the time.
Closes https://github.com/TurboWarp/scratch-vm/pull/332

Thomas Weber 464a9c68dd Support JS Map in externalDeltaToJS for extension compatibility 
Nothing in Scratch uses this

Thomas Weber 6abc33d787 Remove immutable.js (#329) 
Why:
* We use immutable.js 3.8.2 which is ancient and not getting updates
* immutable.js adds 55KB to the bundle, of which we use almost nothing
* immutable.js's treatment of 0 and -0 is nonsensical and would require weird workarounds like https://github.com/TurboWarp/scratch-vm/pull/320
* We don't benefit from the whole immutability thing

What we're doing instead:
* We have our own MonitorState and MonitorRecord classes
* We track dirty-ness at modification time instead of equality checking every tick
* scratch-gui and packager can continue to think we use immutable.js without causing issues in either direction
  * our objects have enough stubs that immutable.js-expecting consumers are ok
  * when receiving an object, we check if it looks like an immutable.js one and ask for the plain JS version so that works okay too

8to16 36bf998aee Fix evalAndReturn with comments at the bottom of a script (#322) 
This is because beepbox's script:
https://cdn.jsdelivr.net/npm/beepbox@4.2.0/global/beepbox_synth.min.js
has a sourceMappingURL comment at the bottom for whatever
reason, causing it to become
//# sourceMappingURL=beepbox_synth.min.js.map;return beepbox;
This is obviously going to break and might also be the case with
other libraries too, hot just beepbox.

GarboMuffin 20f25f252c interpreter: Do not re-evaluate procedure arguments after stop this script or return (#202) 
"stop this script" and "return" would previously cause all the procedure
arguments to be re-evaluated and then discarded. In vanilla Scratch the
worst case is a performance penalty, but with our custom reporters it
can cause infinite loops.

Muffin 9657efb1d4 Shorten Base64Util test cases

tpsntandMuffin 845c374f72 Fix WeDo2.send sends empty message (#192) 
* Fix WeDo2.send sends empty message

WeDo2.send invokes Base64Util.uint8ArrayToBase64(message). However message.arrayLength === undefined. This causes Base64Util.uint8ArrayToBase64 always returning empty string ''.

* Move the fix to base64-util instead
