fix: Import-attributes support

[zermelo-wisen]

• Upgrades Meriah to v5 to support import-attributes.
• Replaces assert keword of old import-assertions with "with" keyword of import-attributes before parsing code with Meriah because Meriah does not support import-assertions.
• Replaces Astring library with the forked version modifed to support import-attributes.
• Adds a test which passes with the fix and fails with "Unexpected token: 'identifier'" error message which is encountered while running CyberChef project tests with appmap-node.

The cause of the problem was the following example syntax in CyberChef project:

import OperationConfig from "./config/OperationConfig.json" assert {type: "json"};

This is called "import assertions." Later it was replaced with "import attributes" proposal and the syntax was changed a bit. Using the new syntax (import attributes), it would be written as:

import OperationConfig from "./config/OperationConfig.json" with {type: "json"};

Resolves #157
