PackageScore fields can be null

[Rexios80]

If a package was recently updated, some of the information in PackageScore can be null. For example: grantedPubPoints and popularityScore. These should be handled by the client.

@Rexios80 In this particular case I believe the correct behavior would be just to have those params nullable. The other option is to set a default value, but not sure if that would be the correct apporoach.

Nullable fields makes the most sense to me

@Rexios80 would you like to do a PR for this? If not I will try to get to it over the weekend

[Rexios80]

I will if I have time. I'm going to have to do some testing to figure out what fields are nullable unless you happen to already know.

[leoafarias]

@Rexios80 if you can double check would be great.
