Fuzz blockers

The following nodes represent call sites where fuzz blockers occur.

Amount of callsites blocked	Calltree index	Parent function	Callsite	Largest blocked function
25	24	scipy.io.matlab._mio5.MatFile5Reader.read_var_header	call site: {node_id}	scipy.io.matlab._mio5._simplify_cells
3	19	scipy.io.matlab._mio5.MatFile5Reader.read_var_header	call site: {node_id}	_streams.ZlibInputStream
1	7	scipy.io.matlab._mio5.MatFile5Reader.get_variables	call site: {node_id}	.list
1	14	scipy.io.matlab._miobase.read_dtype	call site: {node_id}	mat_stream.read
