Record.wr_dat_files: handle multiple files in expanded format.

Benjamin Moody · Benjamin Moody · commit f61d3a19f803 · 2022-09-06T16:01:39.000-04:00
When writing multiple signal files in expanded format, the
samps_per_frame passed to wr_dat_file must be the list of
samples-per-frame *for that particular dat file* (corresponding to the
e_d_signal argument), not the samples-per-frame of the whole record.
