Changes in openfst 1.5.4:

• Adds RemoveSymbol method to SymbolTable
• Prevents underflow when using LogProbArcSelector in random generation
• Makes random weight generators a single template class
• Makes weight Properties constexpr where possible
• Adds check for error when opening files when compiling strings into FARs
• Adds routines for parsing string flags to the scripting API

Changes in opengrm-ngram 1.3.1:

• Updated unit test scripts to use random file names and directories, to avoid collisions with multiple processes.
• Fixed ill-formatting in error handling.
• Improved reading of large files of ngram counts with ngramread.

The sphinxtrain build is a simple rebuild due to the other two updates.
