Should we include some very common crates as dependencies by default?

[bjoernQ]

While not needed to build the generated code some crates are very common to use - maybe it would be convenient to always have them already included

Currently only critical-section comes to my mind but probably there is more?

I added critical-section in #60 - if anyone identifies more common dependencies we can collect them here - otherwise we can close this at some point in time

I think we want to add the deps that are needed for the template as it means we'll have to keep updating those too. I suppose stable crates like critical-section are fine.

Closing.
