Add statement interruption support
...
This adds an interrupt() method to Statement that allows apps to
interrupt a running statement. Please note that this is different from
`sqlite3_interrupt()` which interrupts all ongoing operations in a
database. Although we want to support that too, per statement interrupt
is much more useful to apps.

Merge 'Add support for soundex() function' from flaneur
...
add [soundex](https://www.sqlite.org/lang_corefunc.html#soundex ) scalar
function.
it seems that sqlite did not enable `soundex()` function by default
unless build it with `SQLITE_SOUNDEX`, while the sqlite in the ci
workflow did not enable it. this pr skipped the test over `soundex()`
temporarily in the `scalar-function.test` file.

Merge 'Add bitwise vdbe ops' from Preston Thorpe
...
Love the project, been following your blog posts for quite a while now.
I asked on Discord prior to submitting this, just because I didn't see a
specific issue for this feature... but if this PR is out of scope for
contributors, feel free to close it as I just had a good time hacking on
it.
This PR adds support for `BitAnd`, `BitOr`, and `BitNot` operators in
the vdbe, as well as unary expressions applied to aggregate functions;
which was needed in order to have `BitNot` support the same tests that
the other operators had.
*Also added unary negation of function calls, because since unary ops
were added, I figured adding support for the other existing unary
operator might be in scope, but lmk if not.
Let me know if there is any more tests or documentation to add/improve.

Merge 'Add support for CASE expressions.' from Alex Miller
...
There's two forms of case:
CASE (WHEN [bool expr] THEN [value])+ (ELSE [value])? END
which checks a series of boolean conditions, and:
CASE expr (WHEN [expr] THEN [value})+ (ELSE [value])? END
Which checks a series of equality conditions.
This implements support for both. Note that the ELSE is optional, and
will be equivalent to `ELSE null` if not specified.
sqlite3 gives the implementation as:
```
sqlite> explain select case a WHEN a THEN b WHEN c THEN d ELSE 0 END from casetest;

Merge 'impl order by desc' from lemonwx
...
Hi all,
I attempted to implement the `order by desc`, which mainly consists of
the following two parts:
1. for cases where the primary key can be utilized, I implemented
`push_scan_direction` to push the scan direction down to the `Scan`.
2. for cases where the primary key cannot be utilized, I re-implemented
the sorting in `Sorter::rewind` based on whether it's desc or asc.
there is also some related work to be done, such as sort using secondary
index, I will attempt to do next.
Please help review this and let me know how I can improve it, thanks in
advance
