New elldata package update (conductor up to 210000)

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Hello PARI users,

This month, elldata is reaching conductor 210000.

I have updated the optionnal PARI package elldata to the 
latest version of J. E. Cremona Elliptic Curve Data
<http://www.warwick.ac.uk/staff/J.E.Cremona/ftp/data/INDEX.html>

This also changes generators for some curves of degree between 180000 and 190000
that were not saturated.

This package contains elliptic curves defined over the rationals representing
all isogeny classes for all conductor at most 210000. Theses data are needed by
ellsearch and ellidentify and require PARI/GP 2.2.11 and up.

The package can be downloaded from
<http://pari.math.u-bordeaux.fr/packages.html>

Thanks to John for providing the new curves!

Cheers,
Bill.
