Reascript has wrong marshalling for byte strings

[skirsdeda]

Some functions have arguments which need byte strings as opposed to strings containing text,e.g.:
MIDI_InsertEvt - msg
MIDI_InsertTextSysexEvt - msg
I guess there are some other functions like that.

In reaper_python.py msg argument of these functions is treated like all other strings:
rpr_packsc(p4)
which in turn does this:
str(v).encode()

The sane way to pass msg to InsertEvt from Python would be:
msg = '\xFF\x2F\x00' # byte string containing end of track event
RPR_MIDI_InsertEvt(take_id, False, False, ppq1, msg, len(msg))

This doesn't work with str(v).encode().
So instead of rpr_packsc(p<smth>)
c_char_p(p<smth>) should be used.

MIDI_InsertEvt definition in reaper_python.py would be:
def RPR_MIDI_InsertEvt(p0,p1,p2,p3,p4,p5):
a=_ft['MIDI_InsertEvt']
f=CFUNCTYPE(c_byte,c_uint64,c_byte,c_byte,c_double ,c_char_p,c_int)(a)
t=(rpr_packp('MediaItem_Take*',p0),c_byte(p1),c_by te(p2),c_double(p3),c_char_p(p4),c_int(p5))
r=f(t[0],t[1],t[2],t[3],t[4],t[5])
return r
