Here is a small script to measure the impact on code size by dependencies.

When running `go build -work`, the results are kept and a `WORK` is output.

Exporting this variable and running the script, will show a list of sizes.

It shows the size (in KB) of each static library built for each module.

```console

$ go get -work github.com/afbjorklund/build-size

If building a library instead of a program, then it can be built as an `.a`.

This is done with `-buildmode=archive`, instead of using `-buildmode=exe`.

To visualize the module sizes, you can use the excellent [space-radar](https://github.com/zz85/space-radar):

Just save the output as a text file, and use the "Load DU file" button...
