Analysis of non-CHEOPS data with pycheops

[lucaborsato]

Dear Pierre, it would be interesting to implement a Dataset for the data coming from different telescope/mission, such as Kepler/K2 and TESS. SingleVisit: read fits or txt file with time, flux, flux_err, diagnostics (custom or pre-defined list with 0 values if not needed) possibility to specify to compute LD coefficients for the correct filter MultiVisit: load SingleVisit analysis and automatically add LD coefficients for filters different from CHEOPS Best, Luca
