Added processing of the typeStr attribute; it returns directly the token's datum type in string form.

[*] The wrapper of the search function for the ticker token by the hash of the transaction in ledger, was commented out for some reason, I fixed it and checked the performance of the wrapper.

[*] The fill function has been redesigned, now it takes three arguments of the subscription type, the subscription public key hash, and the network network identifier. The function now uses and processes dap_chain_addr_fill.

[*] Renamed the fill function to fillFromKey this is more consistent with the function that is called inside this wrapper.

[*] Fixed a bug related to getting a dateTime object from a timestamp. Added function to get datum version. Fixed the calling convention and the name of the function to get the size of the datum.

[*] Changed the error related to the fact that the signature of the callback getting an iterator atom has changed.

[+] Added attributes for reading data from dap chain_datum_token_t and dap chain _datum_token_emission_t.

[+] Added a wrapper over dag events and work with dag chains. Everything is geared towards obtaining information about being and information from the event's dag.

[+] Added functions for checking whether a datum, a declaration token and an emission token, and also added functions for getting wrapper objects dap_chain_datum_token_t, dap_chain_datum_token_emission_t. The function of getting the string representation of the datum type has also been added.
