Subject: Bug in read_array_by_index in pyDmdReader v7.3.2

[LNH-596]

In __get_ranged_sweeps_by_index, the call to __get_single_sweep is missing the required sample_values and timestamp_values arguments, causing a TypeError. The method does not allocate buffers via __init_sample_and_timestamp_arrays before calling it, unlike __get_all_sweeps or __get_ranged_sweeps.
Please fix in next release.
