Support Unitful xticks and yticks?

[JeffFessler]

Thanks for this great package. Currently it supports Unitful xlim very nicely, but Unitful xticks leads to an error. This caught me because I often use xticks=[x[1],x[end]] to streamline plots and it fails if x has units. My workaround is xticks=[x[1],x[end]] / oneunit(x[1]) which is fine for now but I wanted to report the issue because it seems like it would be nicely consistent to support having the ticks be specified in the same units as the corresponding axis.

using Unitful, UnitfulRecipes, Plots 
x = 1u"mm" * (1:30)
scatter(x, 2x) # works as expected
scatter(x, 2x; xlim=(10u"mm", 20u"mm")) # works as expected!
scatter(x, 2x; xlim=(1u"cm", 2u"cm")) # works as expected - yay!
scatter(x, 2x; xticks=[1u"cm", 2u"cm"]) # error message

ERROR: DimensionError: 0.13 and 1.0 cm are not dimensionally compatible.

Thanks for reporting. Would be great to support this. Should also be not too hard to implement, we just have to strip the unit from the ticks, just like we to for e.g. the lims:

UnitfulRecipes.jl/src/UnitfulRecipes.jl

Line 37 in ca60ab8

ustripattribute!(attr, axislims, u)

You want to give it a stab? A PR would be awesome!
