build(deps): [security] bump smallvec from 0.6.7 to 0.6.10

[dependabot-preview]

Bumps smallvec from 0.6.7 to 0.6.10. This update includes security fixes.

Vulnerabilities fixed

Sourced from The RustSec Advisory Database.

Double-free and use-after-free in SmallVec::grow()
Attempting to call grow on a spilled SmallVec with a value equal to the current capacity causes it to free the existing data. This performs a double free immediately and may lead to use-after-free on subsequent accesses to the SmallVec contents.

An attacker that controls the value passed to grow may exploit this flaw to obtain memory contents or gain remote code execution.

Credits to @​ehuss for discovering, reporting and fixing the bug.

Patched versions: >= 0.6.10
Unaffected versions: < 0.6.5
