Ephemeris dialog

Remark: In previous version of proastro it was necessary to translate UNIX.406 or other JPL binaries from "big endian" to "little endian"
This stage is not necessary any more, translation "big endian" to "little endian" is automatically done, if needed.

Performances:
The best performances are obtained with ephemeris DE406
who only needs a file of about 200 Mb.
Low precision ephemeris are less fast than DE406 but does not need the binary file DE406.
DE431 must be used for astronomical charts in the far past but require a big file of 2.7 Go.
However performances are little affected in comparison of DE406.
