Remove the parameter queue and use the write_pending flag instead

[Guzz-T]

With these changes, the data to be written is stored directly in the field object, so that the values can also be set directly in the field via value.

This is indirectly a breaking change, as the value of the field changes when set() is called. This was not the case before. @Bouni, was there a specific reason why it was implemented this way?

Previously:

parameters.get(2)        >> 1°C
parameters.set(2, 2) 
parameters.get(2)        >> 1°C

Now:

p2 = parameters.get(2)   >> 1°C
parameters.set(2, 2)
parameters.get(2)        >> 2°C
p2.value = 3
p2                       >> 3°C                        

Relates to #221

Should this be set to False even though nothing has been written at this point? The code could still fail in the next couple of lines? Just wondering if it makes more sense to set it to false after the value has been written and/or read back?

[Guzz-T]

When assigning a value to raw, the write_pending flag is reseted.

I would have first avoided a situation where a error during writing would lead to recurring errors. This most closely resembles the previous behavior, wherever the queue was cleared.

I am also considering whether to offer user-adjustable settings, which would allow the behavior to be configured.
