Some banks do <CCSTMTRS>...</STMTRS> in their OFX files

[iffy]

Splitting off second part of #336 to this new issue.

Note to self: you already have a commented-out test in ofx.test.ts

[romainm]

As the file is currently invalid anyway and cannot be parsed correctly, could you try to apply that fix on the fly if you see that the file is missing the closing tag?

[iffy]

@romainm I definitely could, but I'd be worried about a future refactoring removing the exception. Though since I have a good test file for it (thanks to you), I'll give it a go.
