zping example not compiling

[formula349]

Cloned the sdk repo on a linux machine. Tried running the steps in the README and always end up with this error. This is a 'go run', but the same happened with 'go install', which only worked after a 'go mod init zping' and 'go mod tidy'.

Is this example just too old to be run with current version of go?

I'll take a peek

Ok, I didn't use the README on purpose just to see if it'd build how I normally do things and it does. I ran:

cd /tmp
git clone git@github.com:openziti/sdk-golang.git
cd sdk-golang/example/zping
go build ./...

After that, zping seems to work just fine:

./zping
zping replaces the function of icmp ping tool in a ziti network.
It provides an end to end latency measurement between any two ziti identities in
a ziti network and like icmp ping will provide the following metrics upon completion
of the ping session: min, max and mean latency and standard deviation as well as % loss.
zping uses the addressable terminator function of ziti to direct ping requests to
specific ziti identities.

Usage:
  zping [command]

Available Commands:
  client      zping client command
  completion  Generate the autocompletion script for the specified shell
  enroll      Enroll an identity
  help        Help about any command
  server      zping server command

Flags:
  -h, --help   help for zping

Use "zping [command] --help" for more information about a command.

I'd say we probably just need to make the readme better.

See how this readme works for you:

Ok I removed the go.mod and go.sum that I created with go mod init and now I can build and run it. The go mod init was done because go install wouldn't work... Thank you.
