phydat: Add Tesla unit
...
While this is equivalent to the existing Gs (1 T = 10^-4 Gs), this is
the SI (and thus preferred) unit.

sys/phydat: New phydat_fit API
...
The current phydat_fit implementation the following limitations:
- The API is way more complicated to use than needed
- It doesn't perform any rounding
- It uses `long` in a place where actual width (or better range) of the type
is pretty important.
This commit addresses these limitations and uses lookup-tables to reduce the
number of divisions required.
Before this commit code using it looked like this:
``` C
long values[] = { 100000, 2000000, 30000000 };
phydat_t dat = { .scale = 42, .unit = UNIT_V };
phydat_fit(&dat, values[0], 0, phydat_fit(&dat, values[1], 1, phydat_fit(&dat, values[2], 2, 0)));
```
Now it can be used like this:
``` C
int32_t values[] = { 100000, 2000000, 30000000 };
phydat_t dat = { .unit = UNIT_V, .scale = 42 };
phydat_fit(&dat, values, 3);
```
