Just  a few updates on the new API branch (feature/newapi)

- Implemented array type for channels
- overhauled the PVS channels
- added the relevant API functions
- protected spout by making the csoundGetSpout function return const MYFLT *

I think I am pretty much done with the API revision.

I can take a look at changes for WASM this weekend. (Will see if
Hlodver is available too.)

Here’s a couple of examples showing how to access array channels

1) Directly using a channel data pointer

  CSOUND  *csound;
  ARRAYDAT *adat;
  int   n;

  const char *code = R"ORC(
   instr 1
   kArr[] fillarray 1,2,3,4
   chnset kArr, "test"
   kArr2[] chnget "test"
   printk2 kArr2[3]
   endin
   )ORC";

  csound = csoundCreate(NULL, NULL);
  csoundSetOption(csound,"-n");
  csoundCompileOrc(csound, code, 0);
  csoundEventString(csound, "i1 0 1", 0);
  csoundStart(csound);
  csoundPerformKsmps(csound);

  // access channel directly
  csoundGetChannelPtr(csound, (void **) &adat, "test", CSOUND_ARRAY_CHANNEL
                      | CSOUND_INPUT_CHANNEL);
  
  for(n = 0; n < adat->sizes[0]; n++)
    printf("[%d]: %f \n", n, adat->data[n]);

  csoundDestroy(csound);


2) Using an externally allocated array data, copying from channel (same orc code as above)

  // 1-D array size
  sizes[0] = 4;
  // create array data
  adat = csoundCreateArrayData(csound, 'k', 1, sizes);
  
  csoundStart(csound);
  csoundPerformKsmps(csound);

  // copy data from array channel
  csoundGetArrayChannel(csound, "test", adat);
  
  for(n = 0; n < adat->sizes[0]; n++)
    printf("[%d]: %f \n", n, adat->data[n]);

  // dispose of array data
  csoundDeleteArrayData(csound, adat)

FYI: I paired up with Hlodver today and we went through and updated
the newapi branch for WASM. Unit tests passed and I tested with my
live.csound.com site and it's working for me there for live coding.

(We did some examining of the build and are going to continue to look
at modernizing the wasm and browser code.)

Regarding the build artifacts, I think we'll need a PR opened up for
the branch before any workflows will run.
