TAPE record mode breaks norns encoder callback

[lazzarello]

Initial bug was posted in the norns development thread on lines. The FM7 script [defines a callback for the norns encoders]. When the script is loaded, the encoder callback works as expected, in this instance modifying a floating point number for an engine parameter. When I begin recording with TAPE, the encoder callback breaks and Lua throws the following exception.

stack traceback:
/home/we/norns/lua/core/encoders.lua:57: in function 'core/encoders.process'
lua: /home/we/norns/lua/core/encoders.lua:57: attempt to call a number value (field 'callback')

From the output, it seems that the callback field in the encoders module no longer contains a function after enabling recording, rather it contains a number. I'd imagine getting some kind of debugging environment to inspect the table before and after starting to record could be helpful. Not sure how to do that outside of the REPL.

could you pull master, recompile, and see if you can replicate this?
