mz_version() defined without prototype, causing warning, when MINIZ_NO_ZLIB_APIS defined

[snej]

If MINIZ_NO_ZLIB_APIS is defined, the prototype for mz_version is skipped but the definition isn’t, leading to the following warning or error in Clang when -Wmissing-prototypes is enabled:

miniz/miniz.c:182:13: error: no previous prototype for function 'mz_version' [-Werror,-Wmissing-prototypes]
const char *mz_version(void)
            ^

Looks like this can be fixed by moving the following line #ifndef MINIZ_NO_ZLIB_APIS up above this definition.
