chore(deps): bump blockstack from 19.2.5 to 21.1.1

[dependabot-preview]

Bumps blockstack from 19.2.5 to 21.1.1.

Changelog

Sourced from blockstack's changelog.

[21.1.1] - 2020-08-24

Changed

• Persist etags in UserSession store so they don't always need to be fetched when the page is loaded.

[21.1.0] - 2020-06-05

Changed

• Static storage/ functions used by UserSession are no longer globally exported, as they are wrapped by publicly accessible UserSession methods. Functions that are no longer accesible are getFileUrl, getFileContents, getFile, putFile, deleteFile, and listFiles.
• Removed various static functions that have been replaced by UserSession .
• Delete etags from cached etag map on deleteFile so that new files with the same name can be subsequently created.

[21.0.0] - 2020-01-17

Added

• More Blockstack error codes.
• putFile and encryptContent can now optionally base64 encode data, for a ~33% size increase compared to the default hex encoding which has a 100% size increase.

Changed

• putFile performs client-side validation that data size is within the Gaia hub's reported maximum limit.
• When a string value is passed to putFile and the contentType option is unspecified, it is set to text/plain; charset=UTF-8.
• getFile now throws error on 404 instead of returning null.
• getFile, putFile, deleteFile, listfiles now include error info upon failure.
• getFile can now decrypt using a custom private key
• Several cryptographic operations now use the native Web Crypto APIs when available. This primarily increases the performance of file encryption and decryption, and account seed phrase encryption and decryption.
• The following functions now return Promises: handleSignedEncryptedContents, makeAuthResponse, encryptECIES, decryptECIES, encryptPrivateKey, decryptPrivateKey, encryptContent, decryptContent, aes256CbcEncrypt, aes256CbcDecrypt, hmacSha256.
• putfile now prevents data corruption caused by race conditions by using etag values to verify that the client is updating the latest version of the file.
• putFile now attempts to include etag values in the If-Match header of its request, and sets the If-None-Match header to * if it is unaware of an etag for the file it is attempting to write.
• putFile now returns an etag in addition to the publicURL after successfully writing a file.
• PreconditionFailedError thrown if putFile returns with a 412 response.

[19.4.0] - 2019-09-03

Changed

• Excluded unused bip39 wordlist from dist bundle, reducing bundle size.

[19.3.0] - 2019-08-21

Changed

• Fixed deprecated crypto warning in node.js usage.
• handlePendingSignIn now throws an error when overwriting an existing user session. See issue #680
• Updated jsontokens library to v2.

[19.2.2] - 2019-05-12

Changed

• Updated bitcoinjs-lib dependency to v5 and eliminates node-gyp errors on install
• Fixed bugs when running in a web worker

[19.2.0] - 2019-05-12
