Cursor loading for deposits and withdrawals

[ViktorOshkalo]

Issue

• no full parameters supprort for private/WithdrawStatus and private/DepositStatus endpoints leading to no ability to load more than default 'limit' number of records

Implemented

• Added a separate methods to load deposit statuses and withdrawal statuses by cursor loading. It is because the returning json has a different json scema so it seems immposible to me to implement that in the existing methods

Hi, during development of some shared functionality I also ran into this issue. I had already fixed it in my pending changed which are now available in the latest version, so this PR is no longer necessary. Thanks for the effort either way
