NEOs v0.31.0

Diff since v0.30.2

This minor version includes significant improvements to the astrometry and orbit determination interfaces. In particular:

• The parsing of astrometry, reduction of tracklets and computation of the debiasing corrections have been greatly optimized by avoiding the conversion between UTC and TDB.
• A new method to select triplets of observations for Gauss' method, based on a custom metric, now finds a suitable preliminary orbit even if the observations span a long time.
• The performance of the dynamical models, mainly gravityonly! and nongravs!, is now slightly better due to the simplification of some operations as well as the cleaning of unused variables.
• Jet transport least squares, via jtls, now uses the best fit among the included methods, depends on a convergence criterion instead of a fixed number of observations and, by default, fits an orbit to the mean optical observational epoch.
• The findorbit.jl script has been updated to be compatible with the changes introduced in this minor version.

Breaking changes

The high-level interface remains mostly untouched as most of the changes in this minor version affect internal functions and types.
