Add S350 flux value

[mattpitkin]

As of v1.68 (or maybe from 1.66/67 onwards), so pulsar have an S350 flux value. This can now be extracted from a psrqpy query. Note that there are no pulsars for which the S30, S10G, S20G and S50G are added yet, so these are not listed as parameters available within psrqpy yet.
