chore(deps): Update aws-sigv4 requirement from 0.14 to 0.15

[dependabot]

Updates the requirements on aws-sigv4 to permit the latest version.

Changelog

Sourced from aws-sigv4's changelog.

v0.45.0 (June 28th, 2022)

Breaking Changes:

• ⚠ (smithy-rs#932) Replaced use of pin-project with equivalent pin-project-lite. For pinned enum tuple variants and tuple structs, this change requires that we switch to using enum struct variants and regular structs. Most of the structs and enums that were updated had only private fields/variants and so have the same public API. However, this change does affect the public API of aws_smithy_http_tower::map_request::MapRequestFuture<F, E>. The Inner and Ready variants contained a single value. Each have been converted to struct variants and the inner value is now accessible by the inner field instead of the 0 field.

New this release:

• 🎉 (smithy-rs#1411, smithy-rs#1167) Upgrade to Gradle 7. This change is not a breaking change, however, users of smithy-rs will need to switch to JDK 17
• 🐛 (smithy-rs#1505, @​kiiadi) Fix issue with codegen on Windows where module names were incorrectly determined from filenames

v0.44.0 (June 22nd, 2022)

New this release:

• (smithy-rs#1460) Fix a potential bug with ByteStream's implementation of futures_core::stream::Stream and add helpful error messages for users on 32-bit systems that try to stream HTTP bodies larger than 4.29Gb.
• 🐛 (smithy-rs#1427, smithy-rs#1465, smithy-rs#1459) Fix RustWriter bugs for rustTemplate and docs utility methods
• 🐛 (aws-sdk-rust#554) Requests to Route53 that return ResourceIds often come with a prefix. When passing those IDs directly into another request, the request would fail unless they manually stripped the prefix. Now, when making a request with a prefixed ID, the prefix will be stripped automatically.

v0.43.0 (June 9th, 2022)

New this release:

• 🎉 (smithy-rs#1381, @​alonlud) Add ability to sign a request with all headers, or to change which headers are excluded from signing
• 🎉 (smithy-rs#1390) Add method ByteStream::into_async_read. This makes it easy to convert ByteStreams into a struct implementing tokio:io::AsyncRead. Available on crate feature rt-tokio only.
• (smithy-rs#1404, @​petrosagg) Add ability to specify a different rust crate name than the one derived from the package name
• (smithy-rs#1404, @​petrosagg) Switch to RustCrypto's implementation of MD5.

v0.42.0 (May 13th, 2022)

Breaking Changes:

• ⚠🎉 (aws-sdk-rust#494, aws-sdk-rust#519) The aws_smithy_http::byte_stream::bytestream_util::FsBuilder has been updated to allow for easier creation of multi-part requests.

  • FsBuilder::offset is a new method allowing users to specify an offset to start reading a file from.
