issues: 930946817

I'm new to both the dogsheep tools and datasette but have been experimenting a bit the last few days and these are really cool tools!

I encountered a problem running my Google location history through this tool running the latest release in a docker container:

Traceback (most recent call last): File "/usr/local/bin/google-takeout-to-sqlite", line 8, in <module> sys.exit(cli()) File "/usr/local/lib/python3.9/site-packages/click/core.py", line 829, in __call__ return self.main(*args, **kwargs) File "/usr/local/lib/python3.9/site-packages/click/core.py", line 782, in main rv = self.invoke(ctx) File "/usr/local/lib/python3.9/site-packages/click/core.py", line 1259, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/usr/local/lib/python3.9/site-packages/click/core.py", line 1066, in invoke return ctx.invoke(self.callback, **ctx.params) File "/usr/local/lib/python3.9/site-packages/click/core.py", line 610, in invoke return callback(*args, **kwargs) File "/usr/local/lib/python3.9/site-packages/google_takeout_to_sqlite/cli.py", line 49, in my_activity utils.save_location_history(db, zf) File "/usr/local/lib/python3.9/site-packages/google_takeout_to_sqlite/utils.py", line 27, in save_location_history db["location_history"].upsert_all( File "/usr/local/lib/python3.9/site-packages/sqlite_utils/db.py", line 1105, in upsert_all return self.insert_all( File "/usr/local/lib/python3.9/site-packages/sqlite_utils/db.py", line 990, in insert_all chunk = list(chunk) File "/usr/local/lib/python3.9/site-packages/google_takeout_to_sqlite/utils.py", line 33, in <genexpr> "accuracy": row["accuracy"], KeyError: 'accuracy'

It looks like the tool assumes the accuracy key will be in every location history entry.

My first attempt at a local patch to get myself going was to convert accessing the accuracy key to a .get instead to hopefully make the row nullable but I wasn't quite sure what sqlite_utils would do there. That did work in that the import happened and so I was going to propose a patch that made that change but in updating the existing test to include an entry with a missing accuracy entry, I noticed the expected type of the field appeared to be changing to a string in the test (and from a quick scan through the sqlite_utils code, probably TEXT in the database). Given this change in column type, it seemed that opening an issue first before proposing a fix seemed warranted. It seems the schema would need to be explicitly specified if you wanted a nullable integer column.

Now that I've done a successful import run using my initial fix of calling .get on the row dict, I can see with datasette that I only have 7 data points (out of ~250k) that have a null accuracy column. They are all from 2011-2012 in an import that includes points spanning ~2010-2016 so perhaps another approach might be to filter those entries out during import if it really is that infrequent?

I'm happy to provide a PR for a fix but figured I'd ask about which direction is preferred first.
