Not possible to set cookie encode option

[thomasmarr]

One of the options which can be set on cookie.serialize is encode see here

In express-session it is not possible to set this option:

• session/index.js

  Line 161 in 5df613c

  req.session.cookie = new Cookie(cookieOptions);

• session/index.js

  Line 243 in 5df613c

  setcookie(res, name, req.sessionID, secrets[0], req.session.cookie.data);

• session/index.js

  Line 657 in 5df613c

  var data = cookie.serialize(name, signed, options);

• session/session/cookie.js

  Lines 117 to 127 in 5df613c

  	get data() {
  	return {
  	originalMaxAge: this.originalMaxAge
  	, expires: this._expires
  	, secure: this.secure
  	, httpOnly: this.httpOnly
  	, domain: this.domain
  	, path: this.path
  	, sameSite: this.sameSite
  	}
  	},

I believe express-session should expose this, as the default encodeUriComponent is not always the desired behaviour. I would be willing to try and put a PR together for this if it was likely to be merged promptly.

I agree, in my context, cookies are urlEncoded once more by a mechanism I have no control on and I had to patch the module to allow encode to be modified same as other ones.
