[BUG]: Component names colliding with mcdisplay drawcalls crash mcdisplay

[mads-bertelsen]

Describe the bug
If components have names colliding with drawcalls such as sphere, box, mcdisplay will fail with a message such as below:

Syntax error in input!
LexToken(DRAWCALL,'sphere',19,633)

Document steps to reproduce the bug
Steps to reproduce the behavior:

1. Run mcdisplay on an instrument with a component named sphere, for example Unit_test_logger_2D_space (will be updated to avoid this problem at some point)

Expected behavior
Expected mcdisplay to show instrument

Screenshots
Not relevant

OS and McStas/McXtrace version (please complete the following information):

• OS: OS X 14.8.5
• McCode variant McStas
• Version 3.6.14 and recent main built from source

Add your code / dataset
Unit_test_abs_logger_1D_space_tof_to_lambda.instr.zip

Additional context

This is indeed the case, reproduced also here.

A full / healthy solution may require changes both in the mccode-r runtime libs (e.g. cone -> mcdis_cone) and changes to the structure of the Python parser itself (in mccodelib/instrparser.py)

Smallest test I can think of:

DEFINE INSTRUMENT template(Par1=1)

TRACE

COMPONENT multiline = Arm()
  AT (0,0,0) ABSOLUTE

END

gives

mcdisplay template.instr -y
