Compile from source fails with boot error

[fizwit]

Compile from source fails due to the deprecated use of boost::path API.

Boost version: 1.85

Error:

/app/build/ShapeMapper2/2.3/GCC-13.3.0/shapemapper2-2.3/internals/cpp-src/src/MutationParser.cpp:894:17: error: ‘extension’ is not a member of ‘BF’
  894 |         if (BF::extension(BF::path(filename)) == ".gz") {
      |                 ^~~~~~~~~
/app/build/ShapeMapper2/2.3/GCC-13.3.0/shapemapper2-2.3/internals/cpp-src/src/MutationParser.cpp:907:17: error: ‘extension’ is not a member of ‘BF’
  907 |         if (BF::extension(BF::path(outname)) == ".gz") {
      |                 ^~~~~~~~~

Fix with:

-        if (BF::extension(BF::path(filename)) == ".gz") {
+        if (BF::path(filename).extension() == ".gz") {
