play sound block consumes ~48 KBs of data

[microbit-carlos]

Describe the bug

Breaking out this specific issue from:

• https://github.com/microsoft/pxt-microbit/issues/4934

Looking at the binary.js size numbers from this programme, the size difference between removing or including the [play sound] block is ~48 KBs, which is quite a lot for something that would be mostly wrapping CODAL functionality.

To Reproduce

• Load the programme above
• Looking at the binary.js file the total value is 166831
• Remove the play sound block
• Looking at the binary.js file the total value is 118995

Expected behavior A lower memory footprint for the block.

quick note: the 48kb number refers to binary.js size and not the compiled code size. To get an accurate number, you need to download the hex file and open the mbcodal.asm file that appears under the built folder. You can also add ?compiler=size to the url to get more detailed size information in that file.
