Fix bugs with non default hll fields

[markallanson]

The implementation of hll fields with non default values was broken
as it passed the hll kwargs down to the Field without removing them.

Note there is a wider batch of work to support non default values in
the library as new hll fields created, such as HllEmpty need to match
the settings of the field being written to. I have not attempted to
address this, and have simply used the hll_set_defaults to control
things in the tests.

Hi.
Thanks for your PR. Where can I find specification of hll_empty parameters you write about? I can't even see hll_set_defaults function in official postgres-hll extension README. May be I have missed something?

I've found a reference here. I'll accept your PR and release version 1.2.1 as a bug fix and create separate issue for creating extra functionality where you can watch and comment progress or may be collaborate in future, if you are interested in it.

I'll make a release of 1.2.1 a little bit later, as pypi returns "500 Internal Server error" for now when I try uploading packages...

[markallanson]

Thanks. Yeah a lot of this is not documented. You can see the hll_empty stuff in hll.c#2508 where there are variations of the function that allow you to define the params.

Essentially the types you create have to match up to the configuration of the target hll column. It's going to be quite a tricky beast to implement it thoroughly in the client library.

Any chance you could try pushing this to pipy again?

I've tried in the morning, still getting error. I've written an issue to twine repository as I found same closed issues there. Now I wait for their answer. Similar issues found special characters in sources or README.md. But I can't even upload to testpypi previous versions, which have been uploaded successfully to production pypi a long time ago. Strange.

Released v1.2.1

Thanks a lot - really appreciate the effort to push this through.
