bug: certain marker transitions

[darcywong00]

Just noting some of the bugs seen in the source text with the following marker combinations.
At this point, it's faster to fix the source text than debug/update this project

Case 1

Verse bridges currently are expected to go from something like \vs 14-15a
But some texts go

\tx
\vs 14b
\tx
\vs 14c-15a
\tx
\15b-16a

so the current regex can't bridge 14-15-16

Case 2

section header splitting a verse

\tx
\vs 16a
\tx
\vs (section title)
\tx
\vs 16b

The current state machine will start vs 16. then make a section title \ s2, then it doesn't handle \vs 16b correctly

Case 3

Verse bridges are expected to be marked in one of these:

\vs (7-8)a
\vs [7-8]a

so the regex currently doesn't handle:

\vs 7-8 (a)

Likely won't fix these...
