feat: New sqliteIsTransacting() that returns if a transaction is active on the current connection

[bpvgoncalves]

In response to issue #453 I implemented a functionality to allow checking of transaction status.
I cannot find any develop branch so the PR targets the main branch.

It passes the tests:

@bpvgoncalves: 2d4ac14 introduces a problem with the orderly package, found through git bisect. That package fails R CMD check after this commit.

Other packages fail too with the current main branch. Can you please take a look?

My test.sh for git bisect :

#!/bin/sh

set -ex

git clean -fdx src
R CMD INSTALL .
R -q -e 'rcmdcheck::rcmdcheck("~/git/R/orderly")'

Hello. I missed this mail last night. I'm really sorry this change broke something... I'll take a look at it. Best regards.

So... It looks orderly, and possibly other packages, are at some point applying a commit/rollback when no open transactions exists.
The new functions did not allow this behavior by raising an error.

After applying PR #464 it seem to be fixed.
When testing 'orderly' locally I still receive some errors when R CMD check'ing due failure in latex->pdf conversion for docs. devtools::check(document = FALSE) completes successfully.
