czso 0.3.8

• On MacOS Monterey, native curl cannot reach https://www.czso.cz/, making it impossible for R to reach it. So on Monterey machines with the default curl configuration, all functions accessing the server will fail with a message instructing the user to set an option in .Renviron to resolve this issue. This is a temporary situation until the bug is fixed in MacOS or a fix is found in R that does not require the user to set environment variables.
