Mix-up Galileo Health and SISA when spare data are missing

[JulieTls]

Hi,
For Galileo satellites, we've noticed that the function georinex.load inverts SISA and health value when the spare data on line BROADCAST ORBIT - 5 is missing.
For example:

E03 2022 03 01 19 30 00-5.329113919288E-04-3.950617610826E-12 0.000000000000E+00
2.100000000000E+01-1.754062500000E+02 2.726899300587E-09 1.490182316738E+00
-8.136034011841E-06 1.614848151803E-04 1.358985900879E-05 5.440636070251E+03
2.430000000000E+05 3.352761268616E-08-2.121533263633E-01-6.332993507385E-08
9.566859616275E-01 4.578125000000E+01 1.171369975347E-01-5.395939048234E-09
-2.607251459631E-11 5.170000000000E+02 2.199000000000E+03
3.120000000000E+00 0.000000000000E+00 3.259629011154E-09 3.725290298462E-09
2.436840000000E+05

returns health = 3.12 and SISA = 0.
This problem doesn't occur when the spare data is fixed to 0, for example:

E03 2022 03 01 19 30 00-5.329113919288E-04-3.950617610826E-12 0.000000000000E+00

-8.136034011841E-06 1.614848151803E-04 1.358985900879E-05 5.440636070251E+03
2.430000000000E+05 3.352761268616E-08-2.121533263633E-01-6.332993507385E-08

2.437470000000E+05 0.000000000000E+00 0.000000000000E+00 0.000000000000E+00

I think it would be nice to correct this problem in the next version of georinex, since it could be very tricky.
Meanwhile, I've implement the following patch based on regex:
re.sub(r'(E\d{2,2}[^\n]{77,77}\n[^\n]{80,80}\n[^\n]{80,80}\n[^\n]{80,80}\n[^\n]{80,80}\n[^\n]{61,61})\n',
r'\1 0.000000000000E+00\n',
file_content)
Do not hesitate to contact me for further details.
Kind regards,
Julie
