Telepay

What's Changed

Added API endpoints in https://github.com/TelePay-cash/telepay-python/pull/13:
* `transfer`
* `get_withdraw_fee`
* `withdraw`

Also, improved documentation and added more tests.

**Note:** the library has been tested in production and it's ready to use.

**Full Changelog**: https://github.com/TelePay-cash/telepay-python/compare/v0.0.2...v0.0.3

Test version, use it carefully.

Not supporting withdrawals yet. Read the [TelePay REST API reference](https://telepay.readme.io/) for more information.

The previous version was taken to preserve the `telepay` namespace in PyPi, that's why we're using 0.0.2 for this release.
