Compound nodes are ignored in cal blocks.

[jcjaskula-aws]

Here is an MVE:

import openpulse
p = "cal{{1;2;}}"
openpulse.parse(p)
# Program(span=Span(start_line=1, start_column=0, end_line=1, end_column=10), 
# statements=[CalibrationStatement(span=Span(start_line=1, start_column=0, end_line=1, 
# end_column=10), annotations=[], body=[])], version=None)

Please note that body=[]
Removing the cal block returns the expected results ..., body=CompoundStatement{...})....
