add search method for messages with UID greater than X

[HelloSebastian]

maybe fixed #200

Hi @Webklex,

the getMessagesGreaterThanUid function searches for all messages that have a UID greater than or equal to the one passed. The found messages are initialized and returned as MessageCollection.

The proposed method is perhaps not the fastest, because each message is initialized individually. I took the foreach from the ImapProtocol::overview method and adapted it a bit.

I am also not sure if the Query class is the right place for the method. I didn't put the method in the WhereQuery class because it can't be linked to other conditions.

Example:

/** @var Folder $inbox */
$inbox = $client->getFolderByName("INBOX");

$messages = $inbox->query()->getMessagesGreaterThanUid(1600);

It is important to note that the returned MessageColletion may or may not contain the passed UID. Depending on whether the UID is present on the server.

What do you think about the solution, @Webklex?

I have improved the performance by using the populate() method instead of initializing each message individually. The structure is now similar to the get() method.

I have also renamed the getMessagesGreaterThanUid method to getByUidGreaterThanEqual. However, I am still unsure which name is better, or a completely different name would be better.

Hi @Webklex,

I saw that you are planning to release a new version early next week.
#205 (comment)

Is there anything against merging the PR and making it available in the new release?

Do you agree with the naming of the method?

I look forward to hearing from you.
