feat(pow): add difficulty calculation for pre-digishield blocks (5,001-144,999) (#9)

[XC-431](https://dfinity.atlassian.net/browse/XC-431?atlOrigin=eyJpIjoiNGZlYzIwYTg0NmE2NGNhOWE2NmUxZTBiNTdjNzE2NGIiLCJwIjoiaiJ9):
This PR adds the correct difficulty calculation for pre-digishield
blocks (i.e. blocks 5,001-144,999). It follows the previous PR
https://github.com/dfinity/rust-dogecoin/pull/8 which added the logic
for block period 0-5,000.

The main change is the addition of the correct `min_timespan` for a
difficulty adjustment interval allowed for a given block height, as
defined by [dogecoin's difficulty adjustment
algorithm](https://github.com/dogecoin/dogecoin/blob/51cbc1fd5/src/dogecoin.cpp#L57).
