New stack blocks: Play [sound] from (time) secs and Stop [sound]

Referring to #999, if there is a hat block that detects when a sound reaches a time, I think there should also be a corresponding block: play [sound v] from (time). To complement it, another block would be useful: stop [sound v].

Both of these sounds are pretty self-explanatory - play [sound v] from (time) would play the desired sound from a certain time (maybe in seconds?) and stop [sound v] would stop just that one sound.

On a slightly unrelated note, I’m glad that so many new audio blocks are being added!

An example of how this could be used (for pausing music):

when gf clicked
set [time v] to [0]
broadcast [start music v]

when I receive [start music v]
reset timer
play sound [music v] from (time)

when I receive [pause music v]
set [time v] to (timer)
stop sound [music v]

Then you would broadcast “pause music” to pause and “start music” to start again.

Sprites can only play a single instance of a particular sound (successive calls to “play sound” restart the sound), so a “stop [sound v]” block would work fine.

I should clarify that #999 etc. are just proposals we’re thinking about, and we’ll hopefully prototype them at some point, but no guarantees. We’re very careful about adding new blocks. That said we appreciate the thoughtful ideas!
