Channel Export - include_soft_deleted_channels not supported #181
Description
According to the Stream docs for "Requesting a channel export", soft deleted channels are excluded from export by default but can be included by setting the include_soft_deleted_channels option to true.
The include_soft_deleted_channels option is not currently supported by the stream-chat-java SDK at present, looking at the ChannelExportRequestData builder class
Due to company IP restrictions, I'm unable to contribute a PR to resolve this myself. (Sorry!)
