This PR adds an prefix argument to the Address.cash_address method.
If not specified, it defaults to the current prefix if the object was
instantiated from string via a CashAddr, or to the "bitcoincash:" prefix if
it was instantiated from string with a legacy address.

Test plan:
python3 -m tests.test

This is a simple solution to #16

It also provides a solution for issue #13:

>>> from cashaddress.convert import Address
>>> regtest_cashaddr = Address.from_string(
...     "bitcoincash:qr4pqy6q4cy2d50zpaek57nnrja7289fkskz6jm7yf"
...     ).cash_address(prefix='regtest')
>>> print(regtest_cashaddr)
regtest:qr4pqy6q4cy2d50zpaek57nnrja7289fksjm6es9se
>>>

I need to sort out the issue with case.

@PiRK
support uppercase prefixes
bc8d6a9 
If the users specifies an uppercase prefix, the output should be entirely
uppercase. Mixed-case prefixes are invalid.

Note that the case is not recorded in the instance, when creating an Address
from string. If the prefix is not explicitely specified and uppercase, the
output from `Address.cash_address()` will always be lowercase.

Test plan:
python3 -m tests.test
