Version 2.15.3

Added

• New header option "sorting" when reading and writing PBFs. If the header option "sorting" is set to Type_then_ID, the optional header property Sort.Type_then_ID` is set on writing to PBF files. When reading PBF files with this header property, the "sorting" header option is set accordingly.

Fixed

• Do not propagate C++ exception through C code. We are using the Expat XML parser, a C library. It calls callbacks in our code. When those callbacks throw, the exception was propagated through the C code. This did work in the tests, but that behaviour isn't guaranteed (C++ standard says it is implementation defined). This fixes it by catching the exception and rethrowing it later.
