One namespace for sensor functions and types.
Fix discrepancy between topic and indexed topic funcs.
Energy types fixes, make sure we use known ratios.
Sensor fixes, moving certain pin settings and defaults into the sensor
classes, using those in the actual sensor init code.
Energy is still within the sensor module, pending version bump before moving.
proper support for both conversion directions
ratio object stores the scaling, no need to deduce it through the enum
name anymore
we still don't really enforce incompatible units, though,
but it is unclear at what stage the error should come in
fixing redirect, authenticate softap connection implicitly
further support needs DHCP helper, at least that's a standard...
plus, pass F(...) strings where String is accepted by the server
similar to the tasmota ota, reset SDK when AP settings somehow are not
set to default *and* we are in safe mode already
move both even earlier in boot, before the wifi setup happens
using most recent RTOS for reference, allows us to skip Arduino
layer when configuring things. especially useful for UART
re-implementation that does not involve magic pin function modes
adjust our terminal command to really show valid pins and their modes
schedule immediately with module functions, don't wait
more flash-strings in the module and utility functions
support rare condition when body cannot be sent on connect, use poll to send it
don't wait for header line in body, and bail out when done parsing
make sure data is copied into the async variant, and remains there for
the duration of the connection
general async api is... more complicated that it needs to be
until wolfssl / brssl port is here, though, there is no other choice
secureclient config becomes a simple struct, pending further rework
fixing reset always keeping the last value, not the intended size 3... and above.
revert to the previous behaviour where the last element is preserved and
real `capacity` becomes `capacity + 1`. adjust methods accordingly.
and a slightly more verbose median funciton
