convert to uint8_t* for binary data to fix -Wnarrowing build errors

Browse Source 
Newer gcc versions default to -Werror=narrowing when using newer C++
standards (which we do).  This causes issues when we try to stuff a
value like 0xea into a char -- the value is out of range for signed
char bytes.  That's when gcc throws an error:
.../bytereader_unittest.cc: In member function 'virtual void Reader_DW_EH_PE_absptr4_Test::TestBody()':
.../bytereader_unittest.cc:400:55: error: narrowing conversion of '234' from 'int' to 'char' inside { } [-Wnarrowing]
