Need a method to get the channel ID using the current channel name

We need a way to get the channel ID when provided the current channel name as an input. Previously this could be done using the channels.info API method, but now with that method fully deprecated and disabled, we don't have any other reliable method of doing this. We could theoretically post a new message to the channel using chat.postMessage, which returns the channel ID, then remove that message, but this seems like overkill.

The use case is that a user provides a channel name as input, and we want to convert that channel name to an ID and store that ID for later use when posting messages. Obviously the name may change over time, so using the channel ID is ideal.
