performance bottleneck: profile plotting of 1M+ points #1787

this is a placeholder for the future to address this performance issue when for example a cube with 1M channels is loaded in CARTA and user requests a region spectral profile. With v3b2, the GUI becomes basically frozen. The performance bottleneck needs to be studied.

The bottleneck when loading such a cube is addressed by https://github.com/CARTAvis/carta-frontend/pull/1775

@kswang1029 just for the record, does this issue occur in older versions of CARTA?
