update: added support for Harmony One Blockchain

[victaphu]

Changes Changed the way events are retrieved because Harmony One wss end-points restrict the amount of blocks scanned to 1024. Added a parameter called PAST_EVENTS_BATCH_SIZE that indicates the batch size for block scans when using getPastEvents.

If you are modifying the external API of one of the modules, please remember to also change the documentation

• [x] I have updated the associated documentation with my changes
