Switch examples back to satsearch

[gjoseph92]

Until stac-utils/pystac#546 is resolved, pystac is very painful to use, so I'd rather not have it be the lead example.

Partially Revert "Fix for Pystac ItemCollections (#69)"

This reverts commit 98809b4.

FYI I don't think satsearch is being developed anymore. I think it's best for everyone to focus on pystac-client. I believe that @duckontheweb has some time set aside for pystac development coming up.

That said, what versions of pystac & pystac-client are you using? I just reran the example from stac-utils/pystac#546 (comment), and and everything seems OK:

%%time
catalog = pystac_client.Client.open("https://planetarycomputer.microsoft.com/api/stac/v1")
items = catalog.search(
    intersects=dict(type="Point", coordinates=[-106, 35.7]),
    collections=["sentinel-2-l2a"],
    datetime="2019-01-01/2020-01-01"
).get_all_items()

CPU times: user 154 ms, sys: 15 ms, total: 169 ms
Wall time: 1.68 s

and to_dict()

%%time
dict_items = [item.to_dict() for item in items]
CPU times: user 46.4 ms, sys: 402 µs, total: 46.8 ms
Wall time: 44.8 ms

This is with psytac=1.1.0 and pystac-client=0.3.0

Thanks! I hadn't tried updating, but that solves it. I'm glad; I really didn't want to do this (just meant as a stopgap until that issue was fixed). I'll revert this PR and bump the requirements.
