Commands: only check inputs for sanity, not therapy limits.

Updated README to ask the user to configure the pump to enforce limits
and only make sure inputs to the command are sane since there's
no facility in place to report errors back, which is fine given this
proactively guards against bugs, not a valid usage scenario.

(cherry picked from commit 033ace4)

   - Disable end of TBR alert
   - Set TBR duration step-size to 15 min
   - Set low cartridge alarm to your liking
+  - Configure a max bolus suited for your therapy to protect against bugs in the software
+  - Similarly, configure maximum TBR duration as a safeguard. Allow at least 3 hours, since
