HTTPUpdate checked if the new sketch would fit into the current partition free space, which was wrong. Now it checks if it fits into the next flash partition.
A size check for a SPIFFS update is added, this was stil 'to do' from the previous PR.
Still to do: the SHA256 hash could be checked if a server sends it in the request header.
This PR includes PR #2155.
