Fxpmath

* Fix wrap fuction over n_word_max (issue 41).
* Inaccuracy flag is propagated to a new Fxp or resulting Fxp if one or more input Fxp are inaccurate (issue 48).
* New `from_bin` method and function. Set value or create new Fxp from a binary string (issue 49).
* Support to complex binary strings as input format.
* Force to `config.op_input_size='best'` when power operation has an constant operator (non-Fxp). Add warning message. (issue 89).
* Selection of `prefix` for binary and hexadecimal representations.
* Fix `cumsum` function bug when dealing with sizes bigger than 32 bits (windows) / 64 bits (linux) (issue 76).
* Fix `numpy.reshape` function handling. This function was returning optimal size instead of same by default (issue 77).
* Fix negative number parsing in `dtype` string (issue 80).

* Fix FutureWarning in subdtype 'str' comparison (issue 45).
* dtype argument added to `resize` method.
* new method `get_dtype` to get dtype using argument `notation`.
* Docstring of `get_dtype`, `resize`, `reshape`, `flatten`, `set_val`, `astype`, `get_val`, `raw`, `uraw`, `equal`
* Order parameter for `reshape` and flatten methods.
