The removal of Data.Nat.Properties.Simple in v1.0 of the standard library

[MatthewDaggitt]

Hi, this is a ping that the module Data.Nat.Properties.Simple will be removed in the upcoming release of v1.0 the standard library. The module has been deprecated since v0.14.

If you wish to continue using the latest version of the standard library you will need to update the following files:

Helpers/LeqLemmas.agda
Helpers/FinNatLemmas.agda
Helpers/FinEquivPlusTimes.agda
Structures/Experiments/Sidequest/Permutations/PermutationSequences.lagda
Structures/Experiments/Sidequest/Permutations/Vector.lagda
Structures/Experiments/VectorLemmas.agda
Structures/Experiments/Sidequest.lagda
Structures/Experiments/Sidequest/Permutations/SME.lagda

This can be done by replacing open import Data.Nat.Properties.Simple with open import Data.Nat.Properties.

Thanks, we'll fix at least the parts outside Experiments that we want to keep!
