Texas Supreme and Appellate scrapers enhacements

[grossir]

There is more data available in the HTML we already request, that we don't parse (the scraping class is in tex.py)
This is an instance of #889

At least these extra fields we already support are found on the case page, and we don't pick them up

            "judges",
            "lower_courts",
            "lower_court_judges",
            "lower_court_numbers",
            "dispositions",

For an example of dispositions: "Affirmed in Part and Reversed and Remanded in Part".

Some case page examples
