A new ByteArrayConverter class has been added to Elsa.JavaScript that converts byte arrays to Uint8Arrays. In Elsa.Http, the DownloadHttpFile activity now also stores the downloaded file's content in bytes. In addition, various new type aliases have been added to the Elsa.Http and Elsa.JavaScript modules, making it easier to handle non-string responses and the transfer of data.
In DownloadHttpFile.cs, context data now includes response content's file stream. Changes to DefaultDownloadableManager.cs simplify the return statement when no provider is found, directly returning an empty array.
This commit adds a new activity, DownloadHttpFile, which provides the capability to download a file from a specified URL. It introduces supporting classes like HttpFile, FileHttpContentParser, and several extensions methods related to handling HTTP headers and file content. It also contains necessary updates in existing classes to accommodate the new file-download feature.
