feat(AlgoliaAPI): add endowment parsing and unit conversion

[xantror]

This PR adds endowment field parsing and unit conversion for performer height/weight into AlgoliaAPI.

I'm not sure if some sites that use this already have metric values for height/weight or if endowment is limited to penis_size or if it is used differently for females so additional input is welcome.

I tried spot checking with some of the scrapers that used this but all the performers I tried to test had no weight/height/endowment values - needs additional testing.

The only site i managed to test is chaosmen.com where it functions as expected.

Having looked at this more, I don't think you need the separate function and could attempt to get the endowment attribute in the same way that ethnicity is attempted, and then assign performer["penis_length"] with the feet_to_cm converted value, i.e. just two lines.

You shouldn't have to include the gender in the condition either, and can assume that any actor with an endowment attribute populated is referring to their penis length. I can't think what else endowment would be measuring.

The code looks good, but can you provide one or two examples so I can test each conversion taking place?
