func ExtractPackageIndexes

func ExtractPackageIndexes(pkgName, targetedVersion, content string) []int

ExtractPackageIndexes find where a package is defined in a json source file. It returns the block indexes along with name and version. It assumes:

1. the package won't be declared twice in the same block
2. the declaration will be shaped as "<package name>" : "<version or constraints>"
