Enable file system timestamping instead of using a hardcoded date
for all operations. Requires an application supplied implementation
of `get_fattime`. Format of the uint32_t bits are as follows:
31:25 = Year from 1980
24:21 = Month (1..12)
20:16 = Day of month (1..31)
15:11 = Hour (0..23)

* `f_setlabel`
* `f_expand`
* `f_findfirst`
* `f_findnext`
