Further comments

This PR supports encoding for datasets download and upload. The encoding setting is from profile.

[std4lqi]

Looks good to me.

Some background:

The encoding is for the code page used in ISPF, like IBM-1047 (if encoding is not specified), IBM-500, etc. As ISPF shows dataset contents with its own code page, this encoding option in profile helps the dataset will be saved in ISPF code page, in the case of upload. Otherwise, the character like !, [, ], etc might be shown wrong. Some European users suffered from it.

@zFernand0 , @JillieBeanSim Please run it from VS Code to see any problem for user in understanding the purpose of this encoding option.
