1978603203,I_kwDOCGYnMM517xbD,602,`sqlite-utils transform` removes the `AUTOINCREMENT` keyword,4472046,open,0,,,0,2023-11-06T08:48:43Z,2023-11-06T08:48:43Z,,NONE,,"### Context

We ran into this bug randomly, noticing that deleted `ROWID` would get reused after migrating the DB. Using `transform` to change any column in the table will also unexpectedly strip away the `AUTOINCREMENT` keyword from the primary key definition, even if it was not the transformation target.

### Reproducible example

**Original database**

```sql
$ sqlite3 test.db << EOF
CREATE TABLE mytable (
    col1 INTEGER PRIMARY KEY AUTOINCREMENT,
    col2 TEXT NOT NULL
)
EOF

$ sqlite3 test.db "".schema mytable""
CREATE TABLE mytable (
    col1 INTEGER PRIMARY KEY AUTOINCREMENT,
    col2 TEXT NOT NULL
);
```

**Modified database after sqlite-utils**

```sql
$ sqlite-utils transform test.db mytable --rename col2 renamedcol2

$ sqlite3 test.db ""SELECT sql FROM sqlite_master WHERE name = 'mytable';""
CREATE TABLE IF NOT EXISTS ""mytable"" (
   [col1] INTEGER PRIMARY KEY,
   [renamedcol2] TEXT NOT NULL
);

When the processing reaches the line that contains the NUL an exception is raised.

I'm wondering if there is something that can be done in `sqlite-utils` to say ""skip lines with encoding errors"" or some such. I think it isn't super straightforward though as the exception comes from inside the `csv` module that does all the parsing.

Concretely the file is the `KernelVersions.csv` from https://www.kaggle.com/datasets/kaggle/meta-kaggle

This is the command and output:
```
$ sqlite-utils insert --csv kaggle.db kaggle KernelVersions.csv

There have been a number of small issues that are certainly related to my relative lack of familiarity with the toolkit, but that are still surprising. 

For example: a CSV export of the images table (http://laion-aesthetic.datasette.io/laion-aesthetic-6pls.csv?sql=select+rowid%2C+url%2C+text%2C+domain_id%2C+width%2C+height%2C+similarity%2C+punsafe%2C+pwatermark%2C+aesthetic%2C+hash%2C+__index_level_0__+from+images+order+by+random%28%29+limit+100) has nested single quotes, double quotes, and commas that aren't handled by rows_from_file. Similarly, the json output has to be manually transformed to add the column names and remove extraneous information before sqlite_utils can import it.
