Ambiguous wording in `analogReadResolution` note re: setting higher resolution than supported

In the section "Notes and Warnings" there is ambiguous wording:

> For example: using the Due with `analogReadResolution(16)` will give you an approximated 16-bit number with the first 12 bits containing the real ADC reading and the last 4 bits **padded with zeros**.

Consider revising it to:

> For example: using the Due with `analogReadResolution(16)` will give you an approximated 16-bit number with the most significant 12 bits containing the real ADC reading and the least significant 4 bits **padded with zeros**.

This would make it consistent with the wording of the following paragraph:

> If you set the `analogReadResolution()` value to a value lower than your board’s capabilities, the extra least significant bits read from the ADC will be **discarded**.
