Convert Dashlane JSON export to 1Password CSV import.

I've been a Dashlane user since July 2016, and am finally moving to 1Password because of problems with the macOS app and browser extensions, several of which I've reported repeatedly since 2016. In order of severity:

(1) Do not prompt users to install the browser extensions indefinitely. I'm unwilling and unable to install the extensions on certain browsers at work, because of both work policy and personal security preference. For the past two years, the Dashlane app has prompted me aggressively – opening a prompt, opening a browser tab when I try to close that prompt, and then prompting AGAIN when I try to close that browser tab. Dashlane needs to provide a way to opt out of this, for users with legitimate reasons to not want a browser extension to have access to each website they visit, or who use multiple browsers for e.g. work purposes.

(2) The macOS app regularly locks up on my Macbook Pro, and may require a forced restart and several minutes to load and authenticate.
