Parsing of the EXE template fails

Parsing of the EXE template (https://www.sweetscape.com/010editor/repository/files/EXE.bt) fails with

```

Start by reproducing the provided pfp.parse invocation with the EXE.bt template and sample data. Inspect the parser error at EXE.bt line 163, column 77 and the corresponding py010parser grammar or lexer handling. Done means the EXE template parses without the reported ParseError.
