convert arg to bytes object before passing to PyBytes_AsStringAndSize

[anthraxx]

this fixes python3 and ensures for both, python2 and python3 that
the passed argument is a string.

this fixes #14

Hi anthraxx,

Thanks again for your commits to tlsh.

I am wondering if you would know why the Tlsh constructor does not get
called when the tlsh_TlshObject struct is allocated. Tlsh is a member of
that struct, but its constructor has not been called when functions
Tlsh_fromTlshStr(), Tlsh_update(), Tlsh_final(), Tlsh_hexdigest() or
Tlsh_diff() are called.

To work around this problem, I needed to add checks in Tlsh::fromTlshStr(),
Tlsh::update() and Tlsh::final() that if the impl pointer was NULL, then to
do the constructor work (i.e. to call new).

I have googled this topic, but have not found any answers.

Thanks for any input you might have.

Scott
