Add a Function to Retrieve Channels by Address

[KhudaDad414]

Context

I currently retrieve a channel based on its address using the following code snippet:

parsedAsyncAPI.channels().all().filter((c) => c.address() === address)

This approach, while functional, can be verbose and less intuitive for developers who frequently need to access channels by their address.

Proposed Solution

I propose the addition of a getByAddress or a similar function to the parser-api. This function would allow users to directly retrieve a channel based on its address in a more concise and readable manner. The proposed usage would be:

parsedAsyncAPI.channels().getByAddress(address)

Keep in mind there are also other channels you can use to interact with AsyncAPI community. For more details check out this issue.

I like it. My only concern is that multiple channels can have the same address so I think it should become .filterByAddress() instead. The method should return a collection (not an array), so we can filter it using other helper methods proposed at #105.
