+Routine Description:
+
+ Support routine for the PE/COFF Loader that reads a buffer from a PE/COFF file
+
+Arguments:

+ FileOffset - The offset, in bytes, into the file to read
+
+ ReadSize - The number of bytes to read from the file starting at FileOffset
+
+ Buffer - A pointer to the buffer to read the data into.
+
+Returns:
+
+ EFI_SUCCESS - ReadSize bytes of data were read into Buffer from the PE/COFF file starting at FileOffset
