Add summarize as an explicit alias of the function summarise

[william-hutchison]

This pull request adds summarize as an explicit alias of the function summarise. This change increases consistency between tidySingleCellExperiment and dplyr.

• the version should be 1.10.0
• you should have a unit test almost every time you change or add something
• We have some conflicts apparently

[william-hutchison]

Thanks for letting me know. I have added a test for the summarize alias and manually resolved the conflict. It was caused by us both updating the version number. I have now set the version number to 1.12.0, upgrading from 1.11.1.

• Sorry, the version should be 1.11.2

• also, ask to "review" only after at least one github action has passed green.

Error: object ‘aggregate_cells’ is not exported by 'namespace:ttservice'

@william-hutchison I think you have to force the service version in DESCRIPTION like it is in tidyseurat

[stemangiola]

well done!
