Added a function to get an E series. Also added some aliases for voltage and current, allowing `EEV('3v3')` for example. Aliases `A` `V` and `v` added

Previously, EEV(1.2345, precision=4) * 1 would've return an EEV object with default precision of 2. This fixes that, and now the highest precision in a calculation is used. (EEV(1.2345, precision=2) * EEV(1, precision=5) will return an object with precision of 5)

If the class was used with numbers <= to 0, it'd hang.
