tracker/pt: declare floating-point type size in one place
We want double precision for POSIT. It's best for the type to be set in ope place without the need to go over everything while switching it back and forth during tests. Machine epsilon for float is very small as per <https://en.wikipedia.org/wiki/Machine_epsilon>. Also see the absurdly high epsilon of 1e-4 of POSIT that we've had. With floats, making the epsilon lower resulted in change deltas flushing to zero. This typically led to the translation Z value being very unstable in PT. After the epsilon and data type size changes the Z value is stable.
