FR404 Heldenhafter

Improved type of [FR403](https://robocraftgarage.shaf.fun/robots/79). Front-mount gun was not adopted because of the large size of the double-row tank tracks. Better clearance is the additional benefit. The pivot steering problem was solved by shiftiing the front thacks one block off the ground. So normally there are only back tracks touching the ground and turning resistance is much smaller. It can pivot steer smoothly. There are 9 tracks in total. 4 T10, 3 T8, 2 T6. But it still basically keeps the outline of a normal robot instead of a huge track-spam. Less non-cube-blocks are used on this tnak for higher HP under the same CPU limit. The space under the rear row of guns was filled by a pair of T6 tracks. As a result, its main armor could be only 1 block thick, saving CPU for bigger protection area. The guns are dual-mounted. All of these make FR404 a hard unit.
