Bug next to 0 on posit (8,0)

[RaulMurillo]

When setting the posit environment (8,0), there is a small interval (0, (1/(64^2)+1/64)/2) where the posits take a rounding value greater than 0, which is not consistent with the Posit standard.
I guess this is a error on the fraction part of the posit, but I'm not completely sure. But one can check that Posit (1/64).decode() == Posit (1/(64**2)).decode() = (0, -6, 0, 1) and every number between the fisrt one and the mean of those decodes as (0, 0, 0, 0)

Remark: also happens in the negative interval.
