When marking emails as read in a batch, hydroxide will encounter

Sep 18 13:26:21 fedora hydroxide[24839]: 2020/09/18 13:26:21 request failed: PUT https://mail.protonmail.com/api/messages/read: [2024] The IDs maximum is 150

A easy fix is to let the email client or hydroxide devide the batch to smaller blocks and iteratively send such requests (you don't want to do it manually, do you.) Since it's hard to convience email clients to do such "non-standard operation," probably we'd better make hydroxide to do this.
