build failure on 32-bit x86: `error: cannot bind non-const lvalue reference of type ‘uint64_t&’ {aka ‘long long unsigned int&’} to a value of type ‘std::size_t’ {aka ‘unsigned int’}`

The build of SPTAG on the 32-bit x86 port (i386) of Debian GNU/Linux failed due to compile errors.

Start with AnnService/inc/SSDServing/VectorSearch/SearchSsdIndex.h at the LoadTruthTXT calls reported in the build log, then inspect the ReadString declaration in AnnService/inc/Helper/DiskIO.h and the caller from BootVectorSearch.cpp. Reproduce the C++14 build on Debian i386 and confirm that the reported 32-bit compilation errors are resolved.
