Big endian test failure

[jamesjer]

Thank you very much for the versioned tarball. I am attempting to build tlx for Fedora. There is a test failure on our s390x builder; that is a 64-bit big endian architecture:

      Start 33: tlx_string_test
33/40 Test #33: tlx_string_test ............................Child aborted***Exception:   0.30 sec

Running from the command line shows:

DIE-UNEQUAL: tlx::bitdump_le8_type(uint16_t(0x1234)) != "00110100 00010010" : "00010010 00110100" != "00110100 00010010" @ /builddir/build/BUILD/tlx-0.5.20191212/tests/string_test.cpp:139

So the bytes are printed in reverse order. After reading the documentation for bitdump_le8 and bitdump_be8, I'm left uncertain as to what guarantees they make. They seem to be about printing the bits of individual bytes in a particular order. But if you're going to pass multi-byte integers to them, then they have to guarantee something about byte order, too. How do you intend this to work?

Thanks for the issue. the le8 name is wrong, I replaced the functions and fixed the test in 5f2f671
Can you rerun the tests, please?
