Better Scientific notation for 1*10^n
Description
Usually, the 1 before 10^n is omitted. For example, 1x10^2 can be written as 10^2.
Steps to reproduce
import proplot as pplt
fig, axs = pplt.subplots()
axs.format(xlim=(1, 1e4), xscale='log', xformatter='sci')
Expected behavior: [What you expected to happen]
1 is shown as 10^0, 1x10^1 is shown as 10^1 ...
Actual behavior: [What actually happened]

Proplot version
Paste the results of import matplotlib; print(matplotlib.__version__); import proplot; print(proplot.version)here.
3.5.1
0.9.5.post202
I guess this is what you need
axs.format(xlim=(1, 1e4), xscale='log', xformatter='log')
Try using 'log' instead of 'sci'.
I guess this one's a matter of taste. I can see why you'd prefer the consistency of 10^0... I think for the next version I'll change the default behavior to include the 10^0 but add a SciFormatter keyword argument that optionally removes it.
Indeed LogFormatter is probably more appropriate here since it's a log-axis and your major ticks are on exact powers of 10... we may change the default log axis formatter back to LogFormatter for the next version (see #332 for updates).
We could also have SciFormatter automatically remove the leading 1 x for brevity (making the appearance of LogFormatter and SciFormatter identical in this situation), but I guess that would also be a problem with inconsistency... maybe will add another boolean keyword argument for doing that.
@syrte Thanks! Don't know the method of xformatter='log' to use the matplotlib default.
@lukelbd Yes. Omitting 1x sounds good.
