Incompatible with Rack 2.0.8

[iain]

Today Rack 2.0.8 got released. It is not compatible with rack-session-smart_cookie.

Here is the backtrace:

#<NoMethodError: undefined method `to_msgpack' for #<Rack::Session::SessionId:0x00007fe7e3362a68>>

Hi @iain, thank you for reporting this issue. I'll take a look at it over the weekend.
