This PR is part of porting all old scripts #221 and ports
`cool_oneliners` folder

## Summary

### dict.nu
This script has already been ported to `sourced/cool_oneliners/dict.nu`
in

```yaml
from: before_v0.60/cool_oneliners/dict.nu
to: sourced/cool-oneliners/dict.nu
functions:
  dict: sourced/cool-oneliners/dict.nu:2:dict
```

```

### filesize.nu

```yaml

I created `sourced/cool-oneliners/assets/js_map.json` with the data for
this script as it was before

```

### parse_aws_s3_ls.nu
I don't have aws so I just ported the syntax
```yaml
from: before_v0.60/cool_oneliners/parse_aws_s3_ls.nu
to:  null
```
Edit: I considered not porting this script yet because I can't test it
for now
