Fix unit tests for all base conversion functions 

This include cases were artificial constraints were not checked
(eg: between -512 and 511 for `DECBIN`) and some bugs were 32
bits platform were assumed.

The following are covered:

`BIN2DEC`, `BIN2HEX`, `BIN2OCT`,
`DEC2BIN`, `DEC2HEX`, `DEC2OCT`,
`HEX2BIN`, `HEX2DEC`, `HEX2OCT`,
`OCT2BIN`, `OCT2DEC`, `OCT2HEX`
