• What does your PR fix? Fixes issue #
  This PR increases the version of ode to 0.16.1 . Actually I looked into the ode port because I think there was a change in the hash in the tarball (possible due to hg --> git migration?) that caused the existing port to fail (see https://github.com/robotology/robotology-superbuild-dependencies-vcpkg/runs/618225302). However, as I saw that a new patch release went out, instead of just updating the hash of the old version I also bumper the port to the new version 0.16.1 .

• Which triplets are supported/not supported? Have you updated the CI baseline?
  I just updated the version, I do not think it will change the CI baseline.

• Does your PR follow the maintainer guide?
  Yes

It seems a temporary network connection problem (I am able to save the file correctly from that URL) unrelated to this PR.
