Thatch + Grass Stack Buff

<pre>Increases the max stack amount to 128 for both dry grass and thatch<br /><br />The mod doesn't anything new by itself, so should be future-proof.<br /><br />Mod was made as a split from <a href="https://mods.vintagestory.at/thatchexpanded">Thatch Expanded</a> to prevent it being from incompatible/print errors from other mods changing max stack values.</pre>
