Added finding the next free cluster
Added name to long name
Added long name to short name
Added tests for above

Added createLongNameEntry + tests

Moved tests to bottom

Added createShortNameEntry + test

Used the RTC for the date and time for the created short entry

Tidied createEntries


A bit of refactor

No symlinks for FAT32

findNextFreeCluster updates FAT

Reordered tests to better follow the FAT32FS code
FAT32 has no support for symlinks, so removed code around this.
Removed open_args from createNode as it doesn't need it

Added writeEntries + tests

Write the short and long entries to disk
findNextFreeCluster update cluster chain with parent cluster

Added FAT32 write + tests

This Added the ability to create files and directories and write to files.
Added location of the short dir entry for the file so can update the size of the file on disk
Added folders to the test FAT32 directory.
Also fixed minor bug in mkfat32

Added check for destroying the filesystem


Fixed error message for cluster size


Simpler if condition

Spelling


Fixed test

Add a quick format option for mkfat32
Added open implementation

Needed to return a pointer to the file system as `@fieldParentPtr(Fat32Self, "instance", fs.instance)` doesn't work as the the pointer to `instance` is on the stack, then goes out of scope when the init is returned. So will be using free stack space.
Part of #216

Spelling, doc comments and extra test for open file


init -> create, deinit -> destroy

Initial FAT32 interface
Include code page 437

This is now moved to a better location

Fixed initrd doc for allocator


Added test files

 Plus minor extras

Created initial FAT32 filesystem

This initial FAT32 filesystem will parse a stream, which could be a HDD or a in memory filesystem and produce a FAT32 filesystem. This will check if the raw bytes is a valid FAT32 filesystem as descibed in the spec.

This is only a skeleton with no open, read or write functionality.

Part of #216

mkFAT32 use a anytype stream
This allows mkFAT32 to work on a File or a fixedBufferStream or any streram that allows for reader(), writer() or seekableStream() interfaces.

Plus fixed doc comment

Removed the DefaultOrValue
