chapter197 [SORA] blockchain_mini_filesystem, Access to the cluster began possible.

We have implemented the logical sector access from BPB, so-called “cluster access”.
In addition, we have completed the implementation of the bitmap that determines free clusters, and have passed the test.

chapter187, [SORA] About Blockchain mini filesystem structure, part1

First, implement the code that similar to behave as the LBA of a drive.

sector:
The size is SECTOR_SIZE and is the minimum unit, call it with a LBA from 0.

cluster:
The size is SECTOR_SIZE * SECTORS_PER_CLUS and is the access unit, call it with a LBA from mini filesystem.

chunk:
This is one of each file distributed to “fsindex%04d.dat”.
