quick fix spacebar dishes

hull() was not working properly with such a wide bottom shape - since envelope was using a bottom square that was 6.25uX6.25u. that might spell trouble for 2x2 POS keycaps though... this should be changed to a skin() function down the line

CHANGELOG.md

@@ -0,0 +1,16 @@
+CHANGELOG:
+  V2.0.0:
+    * added $fa values for minkowski and shape - so you can customize how much rounding there is
+    * rejiggered `key.scad` pipeline for more clarity and less shapes
+    * implemented "3d_surface" dish - still in beta
+      * super cool though, you can even change the distribution of points on the surface! just make sure you use monotonically increasing functions
+    * created "hull" folder to house different ways of creating the overall key shape
+    * promoted "feature" folder to first-class folder with keytext and switch clearance as new residents
+    * wrote this changelog!
+    * implemented `$inner_shape_type`, use "flat" for less geometry or "disable" to make a completely solid key easily. didn't help render rounded keys though
+    * side-printed keycaps are first class! you can use the `sideways()` modifier to set up sideways keycaps that have flat sides to print on.
+    * it's much easier to make quick artisans now that the inside of the keycap is differenced from any additive features placed on top
+    * `$linear_extrude_shape` and `$skin_extrude_shape` retired in favor of `$hull_shape_type`
+    * added regular_polygon shape and octagonal and hexagonal key profiles
+    * added beta kailh choc
+    * Finally got ISO Enter working correctly!

+# V2.0.0 Cutover
+
+As of February 19th, 2022, the v2.0.0 branch has been merged into master.
+
+This branch completely rewrote key.scad to be much simpler and faster. If you're just starting out, please use master and report any bugs you find.
+
+If you branched off this repo previously, merging to master will probably break any additions you've made. If you need the prior version of the code for whatever reason, v1.1.0 is master just before the v2.0.0 merge. I will be backporting bugfixes to the v1 branch, so if you see v1.1.1 or higher, use that instead.

 1. If your stem isn't fitting in the switch, try upping the slop factor, accessed by giving your keystem function a numeric value (eg `cherry(0.5) key()`). This will lengthen the cross and decrease the overall size of the keystem. The default value is 0.3, and represents millimeters. Note that even if you have a resin printer, you should probably keep the default value; keys printed with 0 slop will barely fit on the stem.

OpenSCAD takes more time to render the more objects you have, regardless of how they interact. Enter `$hull_shape_type = "skin"`.
 
 `skin()` is a list comprehension function available [here](https://github.com/openscad/list-comprehension-demos/blob/master/skin.scad). The gist of it is that instead of having x number of keycap slices unioned together, we give `skin()` a set of profiles and it makes a single object out of it for us. This reduces the number of objects per keycap, which makes it easier to render them.
