 ByteSize is an utility for human-readable byte count representation.
 
+Features:
+* Pre-defined constants for various size units (e.g., B, Kb, kib, Mb, Mib, Gb, Gib, ... PB)
+* `ByteSize` type which presents size units convertible to different size units.
+* Artimetic operations for `ByteSize`
+* FromStr impl for `ByteSize`, allowing to parse from string size representations like 1.5KiB and 521TiB.
