- define maximum value for RPM to 5000 (3600 is the maximin the fan can reach)
- monimod sends previous RPM value if the new value is > 5000 RPMs
- if reads more that 25 times a wrong value, sends a dead word (0x3A00, equivalent to 65536 RPMs)

Increase WDT timeout from ~21ms to 131ms.
It happened that there were errors and restarts of Monimod during pytest testing of i2c.

Thanks to this change the linux kernel may use PEC for these registers
in much easier way.

In pytest, update query flags for TEMP_CURVE_POINTS and TEMP_MATRIX_ROW
registers.

Changes cover:
- fix broken handling of setting row/points (size of temp_matrix_row was too
  small, fan_n in set_tc_curve was read from a wrong type (uint16 not uint8))
- use structures for handling row/points
- add get functionality for row/points (before it was possible to read only
  the transfered data not the actual used)
- iterate over fan entries when getting row/points
- update pytests
  -- update query flags for TEMP_CURVE_POINTS and TEMP_MATRIX_ROW registers
  -- improve write testing of TEMP_CURVE_POINTS and TEMP_MATRIX_ROW
     registers
- update documentation

The line:
*cmds->cmds[cmd_index].data_len = tx_tmp;
triggered the write to memory, which is declared as read-only (const).
Such writes trigger the memory exception.

To make the code simpler and avoid problematic write,
support only writes that has a size of a register.

The fix was tested for PEC.

Without PEC the i2c write transaction is finished before the execution of a callback.
Make the same behavior when the PEC is used.
Triggering a reset over i2c returns write failure if the transaction is not finished.
