New villager professions: Carpenter and Pyrotechnician villager

I really really want a villager that focuses on wood, and one that focuses on fireworks, explosives, gunpowder etc.

There would be 2 new workstations, the woodcutter and the fireworks station respectively. Both would be player interactable (I am looking at you, fletching table) with the woodcutter working like the stonecutter but for wood, and the fireworks station would let you craft fireworks in a more user friendly way with some new combinations added of course, like maybe flight level 4 and 0.5

The carpenter would buy and sell various wood stuff, and I think it would be cool if he worked like the shepherd, where at different levels he would have a different set of logs he could sell... So level 2 he may be able to sell basic stuff like oak and birch and then the possible logs get rarer over time. This would be very helpful. Maybe make it villager biome specific, but we know how the community reacted to that and the librarian. 

The pyrotechnician would sell better and better fireworks as the level progress, among with flint and steel early on as well as tnt and fire charges... He would buy gunpowder, sand and maybe lava buckets...
