Add new HGETDEL, HGETEX, HSETEX to rueidiscompat

[rueian]

go-redis implements new interfaces:

HGetDel(ctx context.Context, key string, fields ...string) *StringSliceCmd
HGetEX(ctx context.Context, key string, fields ...string) *StringSliceCmd
HGetEXWithArgs(ctx context.Context, key string, options *HGetEXOptions, fields ...string) *StringSliceCmd
HSetEX(ctx context.Context, key string, fieldsAndValues ...string) *IntCmd
HSetEXWithArgs(ctx context.Context, key string, options *HSetEXOptions, fieldsAndValues ...string) *IntCmd

We should add them to rueidiscompat as well.
