CE2-related: History-based affine merge candidates

Abstract
In this contribution, history-based affine merge candidates are proposed to be inserted into the sub-block-based affine merge candidate list. After decoding an affine-coded CU, the affine parameters are added to a history table. When constructing the sub-block prediction affine merge candidate list, the affine parameters stored in the history table are combined with MVs of neighbouring blocks to generate the history-based affine merge candidates. Simulation results reportedly show -0.13% BD-rate changing under Random Access (RA) configuration with almost no impact on encoding and decoding time.
