feat: add os.ReadFile to G304 (#706)
In Go 1.16 or higher, the `io/ioutil` has been deprecated and the
`ioutil.ReadFile` function now calls `os.ReadFile`.

Improve the G307 rule
* Add G307 sample code.
The sample should reflect a defered close that leads to data loss.
Due to IDE auto-complete people tend at least log errors, but not
really care about handling.

* Add more G307 sample code. Propose a way to implement

* Remove unused code. Add example that should not return an error but does

* Remove test for synced closed file for now.
Will add this later

Quiet warnings about integer truncation (#586)
Both MinVersion and MaxVersion of crypto/tls.Config are uint16, so the
int16 fields of rules.insecureConfigTLS are too small. GetInt()
interprets integer literals as fitting within 64-bits, so simplify
things by using int64.

fix: WriteParams rule to work also with golang 1.16 (#577)
In go 1.16 the `ioutil` package was deprecated and
the functions should be replaced by their equivalents
in either `io` or `os` packages. This means,
that `ioutil.WriteFile` should be replaced by
`os.WriteFile` instead. To account for this change
and to detect incorrect permissions also for `os.WriteFile`
I changed `filePermissions` rule slightly to allows
specifying multiple packages that can contain given
function and that we should check. This workaround
can be removed after a sufficient time has passed
and after it is decided that checking `os.WriteFile`
is enough.
