chore(deps): bump ascii from 0.9.1 to 0.9.3 in /src/web-client

[dependabot]

Bumps ascii from 0.9.1 to 0.9.3.

Changelog

Sourced from ascii's changelog.

Version 0.9.3 (2019-08-26)

Soundness fix:

Remove unsound impls of From<&mut AsciiStr> for &mut [u8] and &mut str. This is a breaking change, but theese impls can lead to undefined behavior in safe code.

If you use this impl and know that non-ASCII values are never inserted into the [u8] or str, you can pin ascii to 0.9.2.

Other changes:

• Make quickcheck Arbitrary impl sometimes produce AsciiChar::DEL.
• Implement Clone, Copy and Eq for ToAsciiCharError.
• Implement ToAsciiChar for u16, u32 and i8.

Version 0.9.2 (2019-07-07)

• Implement the IntoAsciiString trait for std::ffi::CStr and std::ffi::CString types, and implemented the AsAsciiStr trait for std::ffi::CStr type.
• Implement the IntoAsciiString for std::borrow::Cow, where the inner types themselves implement IntoAsciiString.
• Implement conversions between AsciiString and Cow<'a, AsciiStr>.
• Implement the std::ops::AddAssign trait for AsciiString.
• Implement BorrowMut<AsciiStr>, AsRef<[AsciiChar]>, AsRef<str>, AsMut<[AsciiChar]> for AsciiString.
• Implement PartialEq<[u8]> and PartialEq<[AsciiChar]> for AsciiStr.
• Add AsciiStr::first(), AsciiStr::last() and AsciiStr::split() methods.
• Implement DoubleEndedIterator for AsciiStr::lines().
• Implement AsRef<AsciiStr> and AsMut<AsciiStr for [AsciiChar].
• Implement Default for AsciiChar.
