2d689a668d Add more sanity checks and fix size formatting in ls example (#11) 
* Fix copy/paste errors in ls example so file sizes are correctly output.
* BPB updates.

Fix bug in bpb.active_fat(), because active_fat is
only valid when mirroring is disabled.

Add additional santiy checks to BPB deserialization:
1. bytes per sector must be a power of 2
2. 512 <= bytes per sector <= 4096
3. sectors per cluster must be a power of 2
4. 1 <= sectors per cluster <= 128

Also added some comments relating to conditions that
may be useful to WARN about for BPB deserialization:
Z. bpb.reserved_sectors should be 1
Y. bpb.fats should be either 1 or 2
X. bpb.fs_version should be validated as zero

Add syntactic sugar for:
A. bpb.is_fat32()
B. bpb.sectors_per_fat()
C. bpb.total_sectors()

4528aedc6e Add oem_cp_converter option allowing to provide custom short name decoder 
Encoder is not yet used but will be in future.
This is implemented as static reference for now to avoid adding additional
type parameters to all main types. It should be enough for most of cases
where encoder/decoder does not have any state and can be implemented as
static variable.

7a53215a57 No longer return &str for short names in no_std mode 
Instead methods returning &[u8] were added.
It is API preparation for proper OEM codepage decoding.
Previous behavior would require to store duplicated short names
(one lossy and one real).

217b6046f1 Make disk object type generic (breaking change) 
This change allows for moving an object ownership to FileSystem object
instead of borrowing it. It makes usage of library easier in some cases.
Unfortunately it is a breaking change.
