Add this for up to 64 bit support, for completion:

+    } else if (len <= 64) {
+        UInt64 num = g_malloc(sizeof(guint64));
+        *num = tvb_get_bits64(tvbr->tvb->ws_tvb,tvbr->offset*8 + pos,
len, FALSE);
+        pushUInt64(L,num);
+        return 1;

Btw, I don't understand why the UInt64 userdata encapsulates a pointer
to a UInt64 instead of the uint itself. It makes it a bit harder to
use (you need the g_malloc()).

Also, the UInt64s are leaking memory. I guess the idea is a uint64
userdata can have a reference to memory it doesn't own,
which is why it doesn't define __gc to g_free() the memory?
