* fix: add variable assignment checking as part of MinVersion
* fix: add more code to allow assignment with const
* fix: rework the code and add more test cases for MinVersion
* fix: format linting issue using gofumpt
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.
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.

Made also the rule to not report an issue when encountering function
scoped variable which terminate in a basic literal such as a string.

Currently, rule G204 warns you about every single use of the
functions syscall.Exec, os.exec.CommandContext and os.Exec.Command.
This can create false positives and it's not accurate because you can
use those functions with perfectly secure arguments like hardcoded
strings for example.
With this change, G204 will warn you in 3 cases when passing arguments
to a function which starts a new process the arguments:
1) are variables initialized by calling another function
2) are functions
3) are command-line arguments or environmental variables

The big#Int.Exp used to be vulnerable in older versions of Go, but in the
meantime has been fixed (https://github.com/golang/go/issues/15184).

* Report for Golang errors
Right now if you use Gosec to scan invalid go file and if you report the result in a text, JSON, CSV or another file format you will always receive 0 issues.
The reason for that is that Gosec can't parse the AST of invalid go files and thus will not report anything.
The real problem here is that the user will never know about the issue if he generates the output in a file.

TLS configuration
* Update README
* Remove trailing space in README
* Update dependencies
* Fix the commends of the generated functions
* Add nil pointer check to rule. (#181)
TypeOf returns the type of expression e, or nil if not found. We are
calling .String() on a value that may be nil in this clause.
Relates to #174
* Add support for YAML output format (#177)
* Add YAML output format

* Update dependencies
* Fix the commends of the generated functions
By allowing partial matches of selectors there are chances of collisions
such as those in issue #145, this removes it to expect explicit packages
for each rule.
Closes#145
