Pull request #1895: PIPE-3172: switch off outframe and regridms in default from hifv_mstransform
Merge in PIPE/pipeline from PIPE-3172-hifv_mstransform-should-not-have-frame-transform-enabled-by-default to main
* commit '3029256b3fa22f804d98024d1d868781789a0bf8': PIPE-3172: Expose outframe and regridms parameters in hifv_mstransform
PIPE-3088: remove redundant me.doframe(obs_pos) from inner loop
The observatory position frame is already set once before all loops.
Calls to me.doframe() for the epoch type do not affect the
observatory frame, so re-doing doframe(obs_pos) on every timestamp
is unnecessary.
Timing (compute_zd_telmjd_for_ms, 50 runs, 74 timestamps):
before (d851488da): 12.629 ms per call
after (this commit): 9.204 ms per call
speedup: 1.37x (27% reduction)
Cumulative vs main (22.901 ms): 2.49x speedup
Exact output preserved (verified by test_telmjd_exact).
PIPE-3172: Expose outframe and regridms parameters in hifv_mstransform
Add outframe and regridms parameters to VlaMstransformInputs to allow
frame transformations and regridding control in `hifv_mstransform`, but disabled by default.
