prope is not included in release 1.21.1

[indiejames]

Attempting to run

go get github.com/zyedidia/generic/prope

Results in the following error:

go: module github.com/zyedidia/generic@upgrade found (v1.2.1), but does not contain package github.com/zyedidia/generic/prope

I can retrieve the entire package with

go get github.com/zyedidia/generic

But when I try to use propfe with package main

import ( "github.com/zyedidia/generic/prope" )

func main() { data := "=ℇ∞∏" runes := []rune(data) r := prope.Newrune r.Insert(1, []rune{32}) }

I get the error message

main.go:7:2: no required module provides package github.com/zyedidia/generic/prope; to add it: go get github.com/zyedidia/generic/prope

If I download the 1.21.1 release directly from GitHub I can see that the distribution archive does not contain the `prope` package.
