# Functions
CheckExt3Header checks if byte content contains a valid ext3 header and returns offset where ext3 partition begin.
CheckSquashfsHeader checks if byte content contains a valid squashfs header and returns offset where squashfs partition starts.
GetSquashfsComp checks if byte content contains a valid squashfs header and returns type of compression used.
Init initializes an image object based on given path.
IsOCISIF receives a path to an image file and returns a boolean indicating whether the file is an OCI-SIF image.
IsReadOnlyFilesytem returns if the corresponding error is a read-only filesystem error or not.
NewPartitionReader searches and returns a reader for an image partition identified by name or by index, if index is less than 0 only partition with provided name will be returned if a matching entry is found.
NewSectionReader searches and returns a reader for an image section identified by name or by index, if index is less than 0 only section with provided name will be returned if a matching entry is found.
ResolvePath returns a resolved absolute path.

# Structs
Image describes an image object, an image is composed of one or more partitions (eg: container root filesystem, overlay), image format like SIF contains descriptors pointing to chunk of data, chunks position and size are stored as image sections.
Section identifies and locates a data section in image object.
