As pybricks/support#284 seems to be theoretically possible or might be possible in the future, we can use the automatic program storage to not have to download everytime.

Maybe have a "first time download" process that automatically restarts the hub so the program is guaranteed to be stored?

We have the program start API now with newest pybricksdev

we also need a mechanism to force downloading the program again in case somehow it is lost or outdated.
For new brickrail version on the system probably always download new pogram

allow skipping hub program download
c2b2f3a 
this is possible now that pybricksdev has an API for this

implements #92, but in the future we should be smarter about
when to automatically assume we can skip the download.

we can locally store for each known hub a hash of the program that we last downloaded. When it is different, force download again.

Also if program start fails for some reason, assume wrong or no program is on the hub, and force download.

@Novakasa
remember hub downloaded file hashes
946bb1c 
if the hashes don't match, force downloading the program

this doesn't detect if the hub has new firmware, thus no program, no
idea how to somehow detect that.

drop firmware with frozen io_hub

since we seem to be able to run with dynamic module without problems, and
download speed is not a concern anymore since #92
