Check interfaces against ignorePackageGlobs

This release introduces checking of the interface's package against the configured ignorePackageGlobs values.

Previously, only functions called directly from other packages had their packages checked against this option, however this behaviour was unintuitive. This change checks the interface package as well, ignoring interfaces which originate from a package matching a glob pattern.

Closes #34

Update Dependencies

Closes #30, updates x/tools to latest.

Update Dependencies

This release fixes an issue when running wrapcheck over a Go v1.18 codebase due to an older version of a dependency.

Config to ignore interfaces

This release adds the config parameter ignoreInterfaceRegexps, which provides the ability to specify regex patterns which will ignore calls through an interface with a matching name.

For example:

ignoreInterfaceRegexps:
- [dD]ecoder

The above configuration will cause errors returned by methods called on an interface named decoder or Decoder to skip wrapcheck analysis.

Many thanks to @guillaumeio for the contribution!

Improved compilation of `ignoreSigRegexp`

This releases front-loads the compilation of regexps provided via the config file, enabling immediate error reporting.

It also removes the os.Exit(1) upon failing to compile the regexps, to play nicer with golangci-lint.

Ignore signature by Regex

This release adds the ability to configure wrapcheck to ignore signatures using regex matching using the ignoreSigRegexps config value. Example configuration is below.

# An array of strings which specify regular expressions of signatures to ignore.
# This is similar to the ignoreSigs configuration above, but gives slightly more
# flexibility.
ignoreSigRegexps:
- \.New.*Error\(
